Every year has given us many new plants, and some have proved admirably adapted to parlor cul- ture. } These have received notice, and directions for their cultivation have been given. A chapter has been added on the Culture of Or- chids in the Parlor. These beautiful plants, the élite of the floral kingdom, are yearly becoming more common ; and as their wants become understood we find that their culture presents no special difficulty. A few years ago it would have seemed impossible to grow orchids in the parlor, yet some species do well. 1V PREFACE TO NEW EDITION. arid doubtless experience will enlarge the number. The culture of Succulents as window plants, to which they are well adapted, and the decoration of vesti- bules and halls with half-hardy Evergreens, has de- manded a chapter, and it is hoped the lists given will prove useful. Many subjects have necessarily been briefly treated, but the author hopes the volume may be found to contain all necessary instructions for window gardening. GLEN RipGE, January, 1876. PROTO Crore. As some misapprehensions have arisen, and false statements have been made in regard to the present volume, it is not out of place to preface the present edition with a few words of introdue- tion. The volume is not wholly a new book, but is mostly composed of a revision of chapters which originally appeared in “ Flow- ers for the Parlor and Garden.” ‘The latter work, however, em- braces a large range of subjects, many of which are only of interest to those who have extensive horticultural facilities; and this, in addition to its cost, necessarily places it above the reach of the large number who have only opportunities for window gardening, and who only wish a cheap manual of culture. 3 It was to meet this demand that the volume was originally issued; and the cordial reception it has thus far met in the sale of former editions well attests that it supplies a popular want. While generally the subject-matter is not new, all has been revised, and the whole volume brought up to the point of horti- cultural progress of the present year. This, of course, involved V1 WINDOW GARDENING. the necessity for many changes, and called for the addition of much new matter. | The book is strictly what its name implies,—a manual of “ Window Gardening,” and contains all the information neces- sary for the culture of plants in the parlor. It is not an expensive book, but is a manual of culture for the many; and its price places it within the reach of all who wish to brighten the dark days of winter by the presence of flowers in the window, or who enjoy the home-culture of the pet geraniums, the monthly roses, or the dark-leaved ivy, which often, under the con- stant care of loving hands, thrive better in the chamber-window than in the costly greenhouse. She present volume is but one of a series of cheap works on different horticultural subjects ; another of which (“ Popular Flow- ers”) is already before the public, and of which others are in preparation.

To insure any a a WANE: = degree of success, a careful and con- “iNT ep Bare es = stant attention to details is necessary. ~ pee ~~ These details are all little things in Sy themselves; they scem almost trivial; but () he their observance is imperative, if we would % have our plants in healthy foliage and profuse bloom. It is by the neglect of all, or some of these, that plants grown in rooms usually present such a diseased, unhealthy appearance. Any one of us can call to mind some friend, who, as we say, is always successful with flowers; has blossoms when no one else can, and whose plants are models of health and beauty. We laughingly say, the flowers are his friends; he knows them, and they bloom for him; and so it is, in fact; he knows their peculiarities, attends to their wants, feeds them properly, affords the requisite light and air. Is it then a wonder that for him the grateful flowers put on Ww WINDOW GARDENING. their richest dress of green, and reach out their perfumed blossoms ? But before we give rules for growing window plants, let us leok at these little things, which may come under the head of general instructions. And, first, the SITUATION. We have decided to grow window plants, and we must. “ot choose our window. Let it, if possible, face the east or south; that is, be one which receives the full rays of the morning sun. If we are unfortunate enough not to have such a window, choose the one having the most sun; the afternoon sun is better than none at all. There are very few plants which will flourish without sunlight, and, as a general rule, the more we can obtain the better. If you have a bay window, looking south, you need ask nothing better. HEATING. If possible, choose a room where the temperature at night never falls below forty to forty-five degrees. Let this heat be maintained by an open fire, or by an air-tight stove, on which a large pan of water should be constantly evaporating. A furnace is injurious to plants, by reason 4. WINDOW GARDENING. of its dry heat only; the little gas escaping from our best furnaces is not sufficient to affect plants injuriously. And while speaking of gas, if possible avoid the use of gas light in the room; the unconsumcd gas, always given off, is fatal to delicate plants, and hurtful to the most hardy. If you must use gas in the room, arrange glass doors to shut off your plants from the room, or give up window plants, -and confine yourself to growth in Wardian cases. If a ‘furnace is your only means of heating, provide for sufficient moisture by constant evaporation. Another objection to a ‘furnace is, that it keeps the room too warm for a healthy ‘growth of the plants. The cause of so many window plants showing long, white, leafless stalks, with a tuft of leaves on the end, is, too great heat and too little ight. Proportion the two, and you obtain a short, stocky, healthy growth. In rooms, this proportion is always uncqual. In winter, there are eight hours of sun to sixteen cf darkness; we keep the plant at a temperature cf sixty to seventy degrees all the twenty-four. In a egreen-house, on the contrary, the tem- perature falls to forty degrces at night, rising, by the heat of the sun, by day, to a.maximum of seventy. WINDOW GARDENING. 9) VENTILATION. This must not be neglected; it is as essential to the health of the plant as to the human organization. The best method of providing it is to open the top of the window when the sun’s rays are hottest on the plants. The quantity of air to be given must be proportioned to the outside tem- perature. In cold, cloudy days, but little, and often none, should be given. Care must be taken never to allow a direct stream of cold air to blow upon any plant. WASHING. This must be done frequently. A plant breathes like an animal, and not through one mouth, but thousands. As is well known, the plant draws up its food from the soil through the roots, in a liquid form. This food, very much diluted, must be concentrated, and thus assimilated to the plant. We have in the leaves of the plant, a most beauti- ful arrangement to answer this need. They are filled with ‘* stomata,” or breathing pores, which allow exhalation when moisture is freely supplied, and check it when the supply falls off. These little mouths are found on both sides of the leaf in most plants, but usually on the lower side in by far the greater number. They vary in different plants from 6 WINDOW GARDENING. several hundred to more than one hundred and fifty thou- sand to a square inch of leaf. Now we are careful in our own persons to bathe daily, lest, as we say, the pores of the skin become obstructed; yet we are willing to allow our plants to go unwashed for a whole winter, when the pores are much smaller, more numerous and delicate, than those of the body. The rule is obvious: wash the leaves of the plants, both under and upper sides, at least once a week ; if oftener, the Bete Use water moderately warm, and if the plants become very dirty, a little weak soap-suds is beneficial. This washing should be carefully done with a soft sponge or cloth in the case of plants with thick, pol- ished leaves, such as camellias, oranges, and daphnes, Where plants have hairy leaves, or the substance is soft, water is best applied with a small syringe, fitted with a very fine “‘ rose.” To use this, place the plant on its side in the kitchen sink, syringe it well, turning it from side to side. Let it stand a few minutes for the water to drain off, and return it to its place: it will thank you for its bath by its bright foliage, Never wet the flowers of a plant; water always injures them; nor allow drops of water to stand on any leaves in the sunshine: the rays of the sun form a focus in the drop of water and scorch the leaf. Once a WINDOW GARDENING. rf month, at least, wash the stem and branches of all the hard- wooded plants with a soft sponge dipped in lukewarm water; this prevents the lodgment of insects, and con- tributes to the health of the plant. | WATERING Is one of the most difficult subjects to prescribe by rule, yet there are some rules of general application. Let it be always done with a watering-pot with a fine rose, such as may be procured at any tinman’s. The advantage of this is, it allows the water to fall drop by drop over the whole surface of the soil, whereas, if a pitcher is used, the plants are deluged, or holes made in the earth by the stream of water, and the roots not unfrequently dis- turbed. Let it be done regularly; the morning is the best time, and once a day. The surface of the soil should never be allowed to become perfectly dry, nor should it be sodden with moisture. The temperature of the water used is of vital importance. It should neither be cold nor.warm, but just the temperature of the atmosphere of the room. Thus no check, or chill, or undue excitement is given to the roots, both roots and branches being equally warm. 8 WINDOW GARDENING. A good plan is, to set over night a large pan of water among your flowers, then you will be sure of a sufficiency of water of the proper temperature for the morning water- ing. If this is too much trouble, remember in watering, it is better to have the water too warm than too cold, that is, of a higher rather than a lower temperature than the roots and branches. Now as to the quantity of water. No rule .of universal application can be prescribed. What is life to one class of plants is death to another. The amount of ‘water necessary to make a calla lily thrive would kill a cactus or a heath, and yet the drought necessary for the cactus would be death to the heath. A good rule, however, is never to allow the soil to become dusty or muddy, and with drainage in potting the latter is easily prevented; by regular waterings, the for- mer. Particulars of treatment for different plants will be given when treating of each plant. Never allow water to stand in the saucers of the pots unless the plants are semi-aquatic. Ports. Choose the common flower-pots, selecting those which are light colored rather than those which are brick red; the WINDOW GARDENING. 9 former are soft baked and are more porous; in these, the plants thrive better. Discard all glazed, china, glass, or fancy painted pets; they are not porous, and plants seldom thrive in them. There is nothing neater than the common earthen pot, if kept clean. If, however, something more ornamental is desired, choose some of the fancy pots, — and some are very pretty and artistic in design,—and let them be large enough to set the common pot inside. But there is avery pretty way of fitting up a window which is but little practised; it is, in fact, making the win- dow a flower garden. Build from your window into the room a rounding wooden shelf, say, if the window is large, three feet in diameter from window to outer edge, but at any rate proportioned to the size of the window. On this, place a large box, wood, or earthen ware unglazed, , made to conform to the shelf, and in this put your plants, the taller at the back, the smaller in front, and on each side a climber to run over the top of the window, ona neat wire trellis or on strings. It is desirable to have holes in the bottom of the box to allow superflous water to escape, and to permit this, the shelf should be covered with zinc, which is preferable to 10 WINDOW GARDENING. tin, as it does not rust, and have a low rim all around it, with a little hole to drain off the superfluous water running from the boxes. This is a very pretty way of window gar- dening, but is only to be practised in a very light room; for in a room with but one window, the plants would all grow to the light, and being planted out, they could not be turned as if in pots. A pretty way to grow low plants, | bulbs, and is to fit a box, say eighteen inches wide, and as long as the window, into the window, and then place the taller plants behind in pots.. This box could be turned as occasion required, or as the plants grew towards the light, or could even be removed from window to window. PoTrinG. But a few words are necessary. Always fill the lower inch of the pot with broken potsherds to secure drainage. In filling the soil around. the plants, press it in firmly and establish the plant well. There is no advantage in loose potting. In re-potting, pare off as much of the old, sour soil as possible, being careful not to injure the roots, and place the ball of the plant in the centre of the new pot, filling in all around with fresh soil. As a general rule, plants need . WINDOW GARDENING. 11 re-potting whenever the roots begin to curl round the inside of the pot, or as gardeners say, ‘‘ touch the pot.” This is easily ascertained by turning the. pot down, striking the rim gently against some object by a quick rap, holding the ball of earth and the plant on the palm of the other hand. The plant may thus be taken from the pot and examined, returned again, settled by a smart stroke of the bottom of the pot on the table, and will be none the worse for the inspection. This is also a good way to detect-worms in pots, they generally living near the outside of the ball. The operation must, however, be quickly done, or the worm will be too nimble and withdraw into the interior of the ball. Stirring the surface of the soil is very beneficial, especially for roses, if the roots are not thereby injured. Top dressing is also productive of good effects, particularly with old plants in heavy pots and tubs. It is simply removing the top soil as far down as the upper roots, and refilling the pot with fresh, light, rich soil. MANURING Is not generally needed in pot plants. A mixture of pow- dered or small bits of charcoal in the soil adds a deeper lus- tre to the green of the foliage and brilliancy to the color of 12 WINDOW GARDENING. the flowers. Bone shavings produce the same effect on hyacinths. Liquid manure should be sparingly used, and then very weak. If guano, a tea-spoonful to a quart of water applied once a week. | Liquid stable manure in about the same proportion, applied as scldom. Sort. In potting window plants rich soil should generally be used. The different kinds of soil are, — Peat, which is black earth or decomposed vegetable fibre, usually taken from meadows or damp woods. If a mixture of white sand is with it, it becomes more valuable. - Loam, our common garden soil.’ It may be black or light brown. The best is obtained by taking the turf of old pastures and letting it lay till it all crumbles. Sand, common, or “silver,” such as used by glass makers. It should be free from salt. White beach sand may be freshened by frequent washings. Leaf mould, the decomposed leaves, being the top soil in old woods. WINDOW GARDENING. 13 Manure, the material of an old hot-bed, well rotted and entirely decomposed; the older the better. From these five earths all the soil for green-house opera- tions is compounded. In treating of each plant hereafter we will give its con- genial soil. As a general soil for potting plants, we would say two parts leaf mould, one part manure, one half part loam, one half part peat, one part sand. INSECTs. The only ones troubling house plants are, the green fly, the mealy bug, the scale, and the red spider. Green fly is to be killed by a smoking with tobacco. Put the plant under a barrel with smoking tobacco; let it remain, say fifteen minutes; then give it a syringing. Mealy bug is to be searched for and destroyed. Fre- quent spongings do much to keep down this pest. Scale is to be treated in the same way. Warm soap-suds are peculiarly distasteful to the creature. Red spider, which is seldom found on house plants, is nourished by a dry, warm atmosphere. Water is certain death. Keep the foliage syringed and atmosphere moist, and you will have no red spider. 14 WINDOW GARDENING. PRUNING Is but little required. Should a branch grow out of place or dic, it should be neatly cut off; and a judicious pinching does much to regulate the shape of a plant. Of course all dead leaves and old blossoms should be cut off at once. MN | y| ‘LL teach thee miracles!

Now let us first give in detail, with their treatment, a list of plants suitable for window gardening; then select those for peculiar exposures. PLANTS FOR WINDOW GARDENING. 17 THE CAMELLIA The camellia is a native of China or Japan, from whence it was introduced to British gardens about the year 1739. The name was given in honor of Father Kamel, a Mora- vian priest, whose name, Latinized, became Camellus. The plants first introduced were fairly killed by kind- ness; an error not unfrequently repeated in our day with newly-discovered plants. They were planted in a stove, where the extreme heat soon dried the leaves and parched the plant. We find no further mention of the plant till 1792, when the single red variety (Camellia Japonica) was introduced, and flowered profusely in a common green- house; during the next year many plants of this variety were obtained from China; next we find mention of the double red; soon after, the fringed double white, and many varieties too numerous to mention. Strange to say, the single white was not imported till about the year 1820, and even now it is not common, though a showy and free- blooming variety. The camellia, in its native country, is a shrub or small tree, though Mr. Fortune mentions specimens of the single red as sometimes exceeding twenty feet in height, with 9 od 18 PLANTS FOR WINDOW GARDENING. trunks of proportionate size. This variety is almost hardy, and in the Middle States will often endure the winter; we have known it to survive even our climate, when well protected ; all other varieties are more tender, and few will bear any severe frost without injury. Most of the kinds in our green-houses are derived from Camellia Japonica, though other varicties have, we believe, afforded fine seedlings. CULTURE. The plants should be grown in light loam, or sandy peat and loam, say three parts loam, two parts leaf mould, one part sandy peat; fill the pots one third full of potsherds, to secure drainage, which is indispensable; if the roots of the plant become sodden, particularly during the season of rest, the health of the plant is gone, and years of care may fail to restore its beauty, or remedy the evil caused by a little carelessness in watering. When in a growing state, you can hardly give too much water, and much good may be derived from frequent sprinklings or syringings; this operation, however, must never be performed in sunny weather. One chief care in the culture of camellias is to keep them perfectly clean; dust upon the foliage not only injures the beauty of the plant, but affects its health. The PLANTS FOR WINDOW GARDENING. 19 plants are injured by too much heat; some hold that no artificial heat should be afforded, unless necessary to keep off the frost; but as we wish our camellias to bloom at a season when there is but little else to ornament the house, it is advisable to force them moderately. A. safe rule is, never to allow the temperature to fall below forty degrees at night, or rise above sixty-five or seventy degrees during the day. The plants will thus expand the flowers more slowly and naturally, and there will be no complaint of dropping buds, imperfect flowers, and yellow, sickly foliage. One prime mistake in flori- culture is the little attention paid to uniformity of tempera- ture; a plant can no more preserve a healthy state when exposed to an atmosphere varying from thirty to one hun- dred degrees in a few hours, now dry and now surcharged with moisture, than can an animal. The progress of dis- ease may be more gradual, but it is sure to show itself, and, sooner or later, the death of the plant is the result. The plants, when in bloom, should be shaded, as thus the flowers remain in perfection much longer. Give the plants plenty of air at all times, but during the season of growth protect them from chilling draughts, which would cause the young leaves to curl and stunt the plant. During the 20 PLANTS FOR WINDOW GARDENING. summer, the plants should be placed in a shady, airy situation, out of doors; allow room enough between the plants for free circulation of air; the practice of setting the plants in a mass, under trees, is most objectionable; in the first place, the drip from the branches overhead is injurious, and again, the pots become filled with earth- worms, which are often difficult to dislodge. Another mistake in the culture of camellias is too fre- quently re-potting; while the plant should not be allowed ~to become pot-bound, too much room should not be afforded; a vigorous plant will not require re-potting oftener than every three years; on this point there is, however, some difference of opinion. It is a popular error that the wood of a camellia should not be cut; on the contrary, there is scarcely a hard-wooded plant that bears the knife better; the plant is by nature symmetrical in growth, and, by judicious pruning, perfect specimens may easily be obtained. 3 Pruning should be done after blooming, just as the plants begin their growth. Not more than one flower bud should be allowed on each terminal shoot, if size and perfection of flower are required; remove all others before the buds begin to swell; if delayed longer, little advantage is gained. PLANTS FOR WINDOW GARDENING. FH The florists’ varieties of the camellia are too numerous to mention; the principal colors are red, white, and rose, with all the intermediate shades. The Chinese profess to possess a yellow variety, but we believe it has never been imported; we have seen a variety named “yellow,” the flowers being semi-double, and of a dirty white color. The following are all well-proved kinds, and may easily be procured of any nurseryman. In buying plants, select those of shrubby form, dark green foliage, without any places where leaves have been dropped; look well to see that the plant is free from scale, red spider, or mealy bug; if possible, examine the roots, to ascertain if they are in a healthy state.

Could we have but one camellia, we would choose Double white or Candidissima, for white; for blush, Lady Hume’s blush; for crimson, Sarah Frost. All these are peculiarly adapted for the window. ORANGE AND LEMON TREES. These are favorites for parlor culture, and easily grown. Their treatment is almost identical with that required for the camellia: the same soil, the same temperature, and the same general treatment will produce success in the culture of both. But they are by no means so clean plants as the camellia, being very subject to scale and mealy bug. The only remedy is constant washing, both of the stem and leaves, with a weak soap-suds warm, and applied with a soft cloth. Grown in large tubs they do well in a parlor if kept suffi- ciently cool, and in summer succeed well out of doors. They are thirsty plants and require much water: good drainage is essential. From December to March they will make but little growth; then water moderately. About ‘ the first of March growth begins, succeeded by bloom; then give more water. After the young growth becomes hard- ened, they may be set out of doors if the weather is favor-- PLANTS FOR WINDOW GARDENING. 23 able. A violent wind disfigures the foliage. The young fruit will set in April and May, and will continue green all summer, coloring the next spring, and holding on the tree a long time. At the first approach of frost, the plants should be removed to their winter quarters. The lemon does not bloom and fruit as early as the orange, and is of taller growth and less fitted for the parlor: the blossoms are smaller and purplish outside. The little dwarf ‘“‘ Otahcite orange” is a very common variety, and is always noticeable for its profusion of fruit. The flowers are not as fine as the other kinds, though plen- tifully produced. The fruit is sweet, but without flavor. The Mandarin orange is one of the finest species (dwarf), and producing an abundance of fruit of the most exquisite flavor. Unfortunately it is not common. There are many other larger growing species, all of which produce a profusion of white flowers, exquisitely fragrant. Among these, the myrtle leaved is conspicuous for its shining foliage, and the large shaddock for its enormous white flowers. The former is as symmetrical in its growth as the latter is tall and ungainly. Oranges and lemons raised from seed must attain a large size before they will bloom. The better plan is to graft or ‘24 PLANTS FOR WINDOW GARDENING. rather bud the seedling when about a year old. This operation is simple, but is best performed in a green-house, and it is therefore better to employ some neighboring florist to doit. Any variety may he budded on a common seed- ding stock. Oranges and lemons will livé under neglect, but to grow and flower them to perfection, attention to details, espe- cially of cleanliness, is indispensable. THE DAPHNE. ‘This plant, of which the species are numerous, never receives the care and attention its beauty merits. Every green-house contains plants of the well-known Daphne odorata, sometimes called D. Indica and vulgarly known as ‘* Daphne See It is to this plant we intend more particularly to confine our attention. It is a green-house evergreen shrub, attaining the height of about four ‘feet, remarkable for its long, dark, glossy, green leaves, and its terminal bunches of fragrant, white flowers. It is one of the few old-fashioned plants which the modern rage for novelties has not driven entirely out of cultivation. It has only been thrust into the corners, and left to make its merits known by its beauty and fragrance. PLANTS FOR WINDOW GARDENING. . " Zo It is one of our most popular flowers, and as a window plant -is unsurpassed, flourishing and blooming in situations where most plants would dwindle and die. With gardeners it is no favorite, because, as they say, it is too straggling, and does not form a neat plant. In some respects this assertion is true, for it is impossible to bring into good shape a plant of this variety when once neglected; but by beginning with a young, healthy plant, much may be done, and fine specimens formed. Let it be remembered that the daphne ‘‘ breaks” easily. Prune the plant to a bare stump, and in a few weeks buds will start from all the younger wood; therefore prune severely ; never allow a branch to remain where it is not wanted, let it be as vigorous or luxuriant as it may, and never be afraid of pruning for fear of losing the flowers. The cultivation of the green-house varieties of this plant is almost identical with that of the camellia; the same tem- perature will do for both. The plants should have plenty of pot room, and the pots be well drained. Potting should generally be done in the fall, about the time the plants are housed, when as much of the old soil should be removed as possible without disturbing the roots. 26 PLANTS FOR WINDOW GARDENING. The principal varieties are :— Daphne odorata, the most valuable variety from its sea- son of flowering, which is from December to March, accord- ing to the degree of heat given; leaves oblong, lanceolate, smooth; flowers white or pinkish, in terminal heads, pro- duced in great profusion. Introduced from China about A.D.1770. Propagated by cuttings with great ease. It is one of the best parlor plants we know of, and may be obtained at any green-house at a very trifling expense. D. odorata rubra is a superior, and by no means common variety ; buds, red; flowers, rosy red, with a powerful spicy fragrance. It is a somewhat stronger grower than the last. There is also a variety with variegated foliage, which is no less desirable, though rather scarce. Daphne hybrida is a pretty evergreen shrub, hardy in England, but too tender to endure our winters without protection; flowers purple, produced in terminal heads and in lateral bunches very freely, and pussessing an agreeable fragrance. It blooms at all seasons of the year, but espe- cially from January to April. The soil should be four parts loam, two of leaf mould, and one of sand. PLANTS FOR WINDOW GARDENING. oY THE AZALEA. The Azalea Indica, or Chinese Azalea, is of Asiatic origin. The varieties are innumerable; but the most common and longest known variety is that from which others are but hybrids, Azalea Indica. It is a strong growing plant, with long, coarse, evergreen leaves, producing in clusters of three or more, at the end of the branches red flowers marked with dark spots. This plant may be grown in great perfection, and, as well as all the varieties, is admirably adapted for a window plant. The habit is shrubby, and the flowers are produced in great profusion. A. Indica alba has white flowers, and is a fine old variety. A. Indica purpurea is a variety with blossoms of a light purple color; a profuse bloomer, and of rapid growth. There is also a double variety. A. Indica coccinea is bright scarlet. From these all the fine varieties of the green-houses have been produced. To grow the plants in perfection good drainage is essen- tial. Fill the pot one quarter full of broken potsherds, then fill the soil to within half an inch of the top; soil, a dark peat three parts, one part of loam, one half part of silver sand. 28 P PLANTS FOR WINDOW GARDENING. Frequent re-potting conduces to the health of the. plants. As a general rule, re-pot when the roots run among the crocks at the bottom of the pot. Do not sift the soil; break it into small pieces. l’requent syringing is beneficial, but over-watering must be carefully avoided. Give full sunshine to the plant, but lay a little moss over the pot if the sun is very hot, to pro- tect the roots. | Keep the plant about the temperature prescribed for camellias. ‘ As soon as the flowers fall growth begins. Give plenty of air and sun, for on this growth depends the bloom of the next year. It should be short, close, and the flower buds be set at the end of each branch. Set the plants out of doors in the summer, as prescribed for camellias. Azaleas may be pruned into any shape. This operation should be performed after the flowers have dropped, or after the plant has made its season’s growth. The Azalea is subject to rottenness of the roots, produced by a sodden soil, the effect of over-watering. The remedy is simple: re-pot the plant, and water moderately. Exces- sive dryness, the other extreme, produces yellow leaves and a general unhealthy appearance. PLANTS FOR WINDOW GARDENING. ees The following varieties are of proved excellence, and very distinct. All will succeed in the house. Azalea amena, a lovely variety; flowers double purple; produced in great profusion in midwinter. Indica lateritia, salmon; Danielsiana, bright red; Per- reyana, eae. Murreyana, rose; Indica alba, white: Purpurea, purple; Coccinea, red. Iveryana, pink and white; Variegata, rose and white; filedstanesti, white, striped with red. This list. might be increased an hundred fold. THE ERICA. HEATH. All the plants belonging to this genus are of a low, shrub- by habit, with fine acicular foliage. None are natives of America. The fine varieties of our green-houses, with the exception of the common Lrica Mediterranea, aré natives of the Cape of Good Hope, whence the gardener’s term, ‘¢ Cape Heaths.” The erica will not thrive unless the soil is adapted to its peculiar niture; this is often very difficult to learn, and experience must sometimes be the teacher. The soil to obtain is one of a friable nature, full of vegetable fibre. We find in an old magazine the best directions we remem« 30 PLANTS FOR WINDOW GARDENING. ber to have met in regard to choice of soil. We give them entire for the benefit of our readers : — ‘Heaths, like the azalea and rhododendron, make very small, hair-like roots; and where these latter are growing naturally, will be found a good locality to collect soil for the artificial cultivation of the former. This soil will be found full of decaying organic matter. Take up a handful of it, and you will find a mass of thickly grown, fine fibre, feeling like a bunch of moss. Examine it, and you will see that it is chiefly composed of a black debris of leaves and sticks, thickly interwoven with the roots of surrounding vegetation. An inch or two only of the surface should be taken: all below that is generally inferior, the organic mattcr in it being too much decomposed. “Where this deposit cannot be obtained, a good substitute will be found in turves from old pasture, cut thin, collected in dry weather, and piled in a heap two or three months before using, so that the vegetation in it may be slightly decomposed. Both in its chemical and mechanical prop- erties such a soil is nearly all that can be wished. In pre- paring it, however, it is better to chop it up rather fine, securing a proper mechanical texture by the admixture of coarse sand, broken charcoal, or even a few pebbles, or PLANTS FOR WINDOW GARDENING. ol broken potsherds may be used to advantage for keeping the soil open, to allow free admission for atmospheric gases ; an essential point to be kept in view in the cultivation of all plants, more particularly those in pots, for they are then entirely’ dependent on the cultivator for those conditions which they receive in their natural habitats. “Such a soil as here recommended, kept sufficiently open by any of the above mentioned ingredients, is easily pene- trated by air, thereby increasing its temperature and facili- tating the decomposition of organic matter, during which process various healthful gases are supplied to plants.” In either of the kinds of soil prepared as directed, heaths will do well. The great point to obtain is a loose, porous soil; for this reason the soil should always be broken, never sifted. Another requisite in heath culture, is good drainage; this cannot be too strongly insisted upon; with the best of soil, the plants will suffer if water stagnates around the roots. Fill the pot one fourth full of crocks, and be careful the hole at the bottom is kept open. Never place the pot in a saucer or vessel of any kind, for all water not absorbed must be allowed to drain off. The pots should be clean By PLANTS FOR WINDOW GARDENING. and free from mould or dirt; cleanliness is a point too much neglected. In some sections of our country, much difficulty is expe- rienced in growing heaths; the water containing salts in solution which are fatal to the plant, and we know nursery- men who have altogether abandoned their culture. This seems the case in limestone countries, and we have noticed that heaths, of the tender varieties, when watered with ‘hard’ water, grew sickly and soon died. The best plan is to use only rain water, and pursuing this course no diffi- culty will be experienced. It isa eumaee fact, that in its native countries, the heath is never found in a soil of which the substratum is lime or chalk. In England, heaths are always grown apart from other plants; with us they occupy the coolest part of the green-house. As a general rule, nothing short of frost is too cold for them, and some varieties will bear several degrees of frost without injury. In the wild state, they are distributed over a vast range of country, which accounts for the different temperatures the varieties require; the degree of cold adapted to each, must be the lesson of experience. Among gardeners, heaths are termed hard-wooded or soft-wooded; the former make only a short growth each season, for example, H. Cavendishu ; s PLANTS FOR WINDOW GARDENING, 33 ‘the latter grow a foot or more, as E. Caffra and others. The two kinds require somewhat different treatment; the former being far more difficult to manage; they are, how- ever, far more beautiful, some even dazzling from the bril- liancy of their flowers. Heaths require plenty of air. If crowded, they are subject to mildew; a disease much more easily prevented than cured. Air should be given, if pos- sible, every day; but cold draughts should be avoided dur- ing the growing season. Though heaths are often lost during the winter by grow- ing them in too high a temperature, yet the greatest mor- tality is caused by the heat of summer. With many it is the custom to treat the plants as other hard-wooded plants ; to turn them out doors during the summer, under the shade of some tree. The consequence is, the pots are often exposed to the hot sun, the tender fibrous roots become parched, and the plant dies; or else the drip from the trees rots the roots, producing the like result. Our experience has shown the best plan to be a different treatment for the plants according to their age. Early in June, all young plants should be planted out in a bed with a northern exposure; there they will grow luxuriantly during the sum- mer. Before the September frosts, re-pot them with care, 5} 34 PLANTS FOR WINDOW GARDENING. and winter as old plants. We have found a large bed pre= pared for rhododendrons and azaleas the most favorable place. It is sheltered from the south by a belt of white pines. The soil of prepared peat is suited to the wants of the plant, while the large foliage of the rhododendrons keeps the soil moist by preventing rapid evaporation. For the older plants, we choose a shaded spot, and prepare a bed of coal ashes; slope the bottom to carry off superfluous moisture ; plunge the pots in the bed of ashes, and if the bed is exposed to the sun for any length of time, shade by an awning. Be careful not to crowd the plants; a free circu- lation of air is essential. By this mode, the pots are never exposed to the rays of the sun; the plants receive plenty of light without being burned, and by syringing at evening, and sprinkling (not pouring) water upon the pots and bed, a sufficiency of moisture is secured. Some varieties of the soft-wooded class, such as Caffra rubra and alba, margari- tacea, and others, do best planted out in the full sunshine. The growth becomes short and stout, and the plants are more hardy and less liable to injury. By this course, how- ever, all beauty of foliage is lost, for the plants become of a rusty brown color, which never disappears till the leaves fall. Re-potting should be done whenever the roots become PLANTS FOR WINDOW GARDENING. BE matted or collected at the bottom or sides of the pot; examine to see if they are healthy; if so, give them a larger pot; if not, prune off these which are dead, remove the old soil, and pot in the same size, or smaller, as the case may require. : The custom with gardeners is to pot heaths in the spring, but the grower must be guided by the state of the plant. Insects give but little trouble, where proper regard is paid to the plants. Mealy-bug is sometimes found; the best course to pur- sue, if the plant. a badly infested, is to throw it away, for it is almost impossible to remove the insect; if but slightly affected, pick them off, and wash the plant well with warm soap-suds; whale oil soap is preferable. The same rules apply when the plants are troubled with black or brown scale. rica arborea is particularly subject to attacks of the former, and from the fine, close nature of its foliage, it is very difficult to clean. We have never known our heaths to be troubled by red spider or by aphis. In growing ericas, some attention must be paid to prun- ing, or rather to pinching; the plants should never be allowed to grow tall and spindling; they should be grown 36 PLANTS FOR WINDOW GARDENING. near the glass, and, by frequent turning, prevented from becoming one-sided. Some varieties are of symmetrical form by nature; others require much care to control the too luxuriant branches. Heaths strike freely from cuttings. Take the tops of the -young shoots, about an inch in length; prepare a pot or pan of heath soil; cover this with silver sand to the depth of half an inch; insert the cuttings about half their length, as thickly as you please; cover them with a glass, and frequently wipe the moisture from the inner surface of the glass; keep them slightly moist, and shelter from the direct rays of the sun. When rooted, pot off the cuttings into small pots filled with heath soil, with the addition of a little more sand than is used for the old plants; as soon as the season permits, plant them out to make growth. In re-potting plants or cuttings, care should be taken never to sink the crown of the root lower than it was before; eee raise than sink it. | There is no plant which makes a greater show, or proves more attractive as a specimen, than the erica. In England, it is grown in the greatest perfection, some of the plants © being twelve feet high, and eight feet in thickness. Cana PLANTS FOR WINDOW GARDENING. oT more superb object than such a plant be imagined, when in full bloom? From over five hundred varieties, we cannot be expected to give all that are deserving of cultivation; as before remarked, none are destitute of beauty. The periods of bloom are from January to November; indeed, we may have heaths in bloom every month in the year. The fol- lowing list contains a select variety in colors: — White or Light-Flowered. Arborea, Margaritacea, Grandinosa, Bow- ieana, Jasminiflora, Conferta, Vestita alba, Odorata, Ventricosa, Pellu- cida, Wilmoriana, Caffra alba. Red Flowers. Gracilis, Ignescens, Mediterranea, Caffra rubra. Scarlet or Crimson. Ardens, Cerinthoides, Hartnelli, Splendens, Coccinea, Vestita fulgida, Tricolor. Purple Flowers. Amona, Mammosa, Melanthera mutabilis, Pro- pendens tubiflora. Lilac. Baccans, Suavolens. Yellow. Cavendishii, Depressa, Denticulata. Green-Flowered. Gelida, Viridiflora, Viridis. For window culture, the varieties succeeding best are Caffra rubra and alba, Margaritacea, Arborea, and Medi- terranea. We have been thus diffuse in treating of this plant, because it is a general favorite, yet never seen in good condition in the parlor. 38 PLANTS FOR WINDOW GARDENING. The plant is very hardy, yet impatient of the least neg- lect. A single day’s omission to water, or a drenching, with poor drainage, will kill the plant; yet it will lan- guish for months, and all your care will fail to restore it. If the hair-like roots once become parched or sodden, the plant will die. We do not pegerimead it for a window plant, yet its beauty is worth all the care required; and will not some be fired by ambition to make the heath a window plant? THE CYCLAMEN. This pretty flower is too little known. It is a native of Europe and Asia, some varieties being very abundant in Switzerland and Italy, and is to be found in almost every green-house. It is of the easiest culture. Pot about the latter part of November, in a rich loam, with a dash of silver sand; an addition of about a spoonful of the old soot from a flue will increase the size and brilliancy of the flowers. It must be well incorporated with the soil. Bits of charcoal, broken fine, serve the same purpose. Place the crown of the bulb just above the surface of the soil. The size of the pot must be determined by the size of the bulb ; as a general rule, cyclamen do not require large pots. PLANTS FOR WINDOW GARDENING. 39 Good drainage is indispensable. Keep the plants cool till the leaves are well grown, always keeping them near the glass. When the flower buds begin to rise on the foot stalks, remove to a sunny shelf, where they will soon show bloom. By shading, the duration of the flowers is prolonged. When the bloom is past, gradually withhold water; the leaves will turn yellow, and the plants should be kept dry, in a state of rest, all summer. Do not allow the plants to ripen seed (which they do freely) unless you desire seedlings, to increase your stock. The seed germi- nates easily, bona in rich loam, and seedlings bloom the third year. Some find difficulty in preventing the shrivel- ling of the bulbs during the summer. Our best cultivators, to prevent this, bury the bulbs during the summer in the open border ; take them up about the middle of September, when they are found fresh, plump, and, in good condition for a start. There is one risk, however, in this method: mice are very fond of the bulbs, and sometimes commit great havoc. There is shown in this plant a curious pro- vision of Nature: no sooner has the flower faded, than the stem begins to curl up, and buries the seed capsule in the ground, at the root of the plant; this is designed to pro- tect the seed from birds, and to sow it in a congenial soil. 40 PLANTS FOR WINDOW GARDENING. Good-sized, blooming bulbs may be obtained at any ereen-house, for from fifty cents to one dollar each for the more common varieties. This bulb is particularly adapted for window culture, and will give more flowers, with less trouble, and occupying less space, than any flower we are acquainted with. The more common varieties are C. Per- sicum, white, tipped with rich, rosy purple; C. Persicum album, pure white; C. punctatum, resembling Persicum. All these flower from January to March. C. Huropeum, pinkish purple; C. Huropewm album, pure white; C. hederafolium, very large, rosy purple, a splendid variety. All these bloom from October to January. ss ; \ V7 % Bright gems of earth, in which perchance we see What Eden was, what Paradise may be. CHAPTER. TTI. PLANTS FOR WINDOW GARDENING. THE GERANIUM.

Ayu7y) NDER this head, we propose to treat of the plants usually known, in com- mon parlance, as Geraniums, includ- ing both those horticulturally and botanically known as such, and Pelar- goniums. Between these there are many minute and fanciful distinc- tions, which are only interesting to botanists, and need not concern the amateur. The true geraniums are herbaceous. For window gardening, their treatment must be the same. For the pelargoniums, we are chiefly indebted to the Cape of Good Hope; the geranium is found, in some of its varieties, in Asia, Europe, and America; two of the family, our ‘‘ wild geraniums,” being familiar to us all as among the wild flowers of spring. The scarlet, or horse-shoe geranium, so called from the color of its flowers, and the dark marking of its leaves, is a very common and popular window plant. The rose, oak, 8 * PLANTS FOR WINDOW GARDENING. 43 and nutmeg geraniums are commonly grown for their fra- grant leaves, and for their hardiness, as they can endure more hard usage than most plants. The general fault in geranium culture is, crowding. The plants need light and air on all sides, and unless this is afforded they soon become one-sided, long-drawn, and strag- gling, with but few leaves, and these in a tuft at the end. The blossoms are small and few, and the whole plant pre- sents a picture of vegetation under difficulties. The: fine varieties of pelargonium, called ‘‘ Fancies” by florists, it is useless to attempt to grow to any perfection in the house. They need constant care; and the rules for growing them as specimens, laid down by English florists, are sufficiently confusing and contradictory to involve the amateur in a maze of difficulty. Light, air, and cleanliness are the three primary rules for growing geraniums. The horse-shoe and high-scented vari- eties are not troubled by insects. The pelargoniums (large- flowered geraniums), require constant attention to keep them free from the green fly, which increases upon them with wonderful rapidity. If the weather is warm, and the plants at all affected by the fly, they should be aoalad once in ten days, and frequently syringed. Surely the beauty of 44 PLANTS FOR WINDOW GARDENING. the flowers will compensate for any trouble. To prevent ‘‘drawing,”’ that is, the growing of the plants towards the light, all geraniums should be frequently turned, which will give a well-proportioned plant. If the plants grow too tall, pinch out the top; all the axillary buds will then break into lateral branches. Again, if the side branches become too close, prune them out fearlessly. ‘The geranium breaks easily, and you need never be afraid of killing the plant, even if you prune it down to a bare stump. Soin. Pelargoniums and geraniums require a strong soil; that is, good sound loam, such as will grow melons. The top of a pasture will answer well. Let it be carted home and laid up in a long ridge, so as to expose as large a surface to the air as possible. Keep it clear of weeds, and let it be turned over every little while. To two parts of this loam, add one part. of two-year-old cow dung, well turned over. Old hot-bed dung will do nearly, but not quite as well. Then add about one part of river sand’ and bits of charcoal, mixed. Let all these ingredients be kept in separate heaps till wanted for potting, then mix them in the above propor- tions, and use them moderately dry. This compost should PLANTS FOR WINDOW GARDENING. 45 be used to bloom and grow the plants in. For the winter season, use a small quantity of leaf mould instead of dung. Fresh soil is always to be preferred, for old soil is apt to become cloddy and sour. PorTina. All being ready, put the drainage in a suitable sized pot. Place first a suitable crock, or a large oyster shell over the hole; then lay a few large crocks upon that, and smaller upon those, so that the drainage may occupy about three fourths of an inch. Place a thin layer of moss upon the drainage, and upon that a sprinkling of soot or charcoal dust; after that a thin layer of the rougher parts of the compost, and finally a layer of soil. Then turn the plant out of the old pot, pick out the old drainage, and loosen part of the old roots, spreading them over the new soil as much as possible. Then see that the collar of the roots is just below the rim of the pot, and fill in around the ball with the fresh soil, pressing it down gently as it is put in. When the pot is full, give it a smart stroke or two upon the bench to settle the soil; level it neatly, leaving it about half an inch below the rim of the pot. This finishes the potting. Then give .a good watering of tepid water. 46 PLANTS FOR WINDOW GARDENING. For four or five weeks, while new roots are running into the fresh soil, they will not need a large supply of water; but when the roots reach the sides of the pots, and the leaves and shoots are advancing in growth, then water will be required in abundance. They should never be allowed to flag. After a hot, sunny day, let the plants, in addition to the water at the roots, have a gentle syringing.- Exercise dis- cretion, however, on this point. The geranium is a spring and summer blooming plant. It is very difficult to obtain a flower from December to April; therefore, during the winter it should be kept cool, and moderately dry. About the first of February re-pot the plants, give more heat, sun, and water, and your plants will bloom profusely in May. The varieties grown only for their leaves may have more generous culture during the winter months. VARIETIES. Ivy-leaved geranium (P. lateripes), is a pretty trailing species, with ivy-shaped leaves and purple flowers in the summer. There is also a variety with white flowers. It is PLANTS FOR WINDOW GARDENING. — 47 a pretty window plant, and always does well. It needs plenty of light, sun, and generous culture. The varieties of horse-shoe geraniums (P. zonale hybrids), are all good window flowers, and will often bloom in winter. The following are the best old varieties : — Scarlet. Dazzle, Tom Thumb, Defiance. ‘Cerise. Cerise unique. Pink. Rosa mundi. White. Boule de Neige, Lady Turner. Variegated Leaved. Flower of the Day, Golden Chain, Alma, Bijou. These latter varieties need a green-house to develop the rich colors of the foliage, yet they do well as bedding plants in the summer. P. graveolens is the common rose geranium. THE VERBENA. There are few plants which lend more beauty to the flower garden in summer, or enliven the green-house in the winter and early spring months in a greater degree, than the verbena. From the variety of colors, the rapidity of propagation, the little care needed to bloom the plant in per- fection, and the abundance of blossoms, it is, and always. must remain, a universal favorite. 48 PLANTS FOR WINDOW GARDENING. In addition to these advantages, the facility with which new varieties are raised from seed, render it a favorite with the amateur; and in no collection do we fail to find the verbena, in some of its many varieties. It is a difficult task to prescribe the culture of a plant so well known, and which will grow and flourish under such a variety of circumstances, and in such different situations. As every one has grown verbenas, each has his own peculiar mode of treatment, if, indeed, a flower req:iiring so little care can be said to have peculiar treatment. In writing of a plant, from which seedlings are produced with such ease, and which sports into such an infinite variety of colors and shades, we cannot be too careful in expressing a decided opinion. Every year new seedlings are ‘‘ brought out,” and latterly the varieties have so mul- tiplied that it is very difficult to choose those really worthy of cultivation: the favorite of this spring may, after a year’s trial, be cast aside as worthless, for it may not be found worthy of general cultivation, or better varieties may have been originated. Our verbena was introduced into England from Buenos Ayres, where it is indigenous, by Mr. Hugh Cumming, an ardent lover of nature, about the year 1825. PLANTS FOR WINDOW GARDENING. 49 The first, and for a long time the only variety cultivated, was Verbena melindres, or chamedrifolia; but it now appears lost among the new and superior kinds which have been raised from seed. In form, it has been repeatcdly excelled, but its creeping habit and abundance of bloom. must always recommend it, though we doubt if at the present (ime it can be obtained at any of our green-houses, and probably few of our younger cultivators have ever seen this once popular variety. The color is scarlet, and though perhaps equalled, can never be excelled. Many other earlier varieties might be mentioned, but, although interest- ing, it would too much extend the limits of this article. Verbena multifida, with lilac purple flowers, was intro- duced from Peru; Verbena Wingate! with rose crimson flowers, from Brazil; and from these, and a few other varieties and seedlings, have sprung all the numerous varieties, many hundred in number, which may be found in extensive collections. The credit of introducing this plant into the United States belongs to Robert Buist, of Phila- delphia. About the year 1835, from seed received from Buenos Ayres, he raised. the first white, pink, and crimson verbenas. The plant soon became generally known, and was every where a favorite; in the floral world it caused 0 PLANTS FOR WINDOW GARDENING. quite an excitement, and the original kinds were soon sur- passed, in every respect, by newer seminal varieties. The culture of the verbena is very simple. ‘The plants will bloom with very little care, but to grow them in perfec- tion requires attention; of thousands of plants of any size, ‘scarcely one is a fine specimen. Let us, beginning in early ‘spring, trace the plant, as generally grown, and then see ‘chow much a little care might increase its beauty. About the first of February, cuttings of the young shoots are taken from old plants: in a sandy loany a few wecks, and sometimes a few days, will suffice to root them; they are then potted off into thumb pots, aie if placed near the ‘glass, will soon show a terminal flower. As soon as the scason is sufficiently advanced, these young plants are bed- ded out, and, in favorable seasons, soon form a conspicuous feature in the flower garden, continuing to bloom till long after the early frosts. About the first or middle of Septem- ber, the gardener begins to re-pot his plants for winter, and the common practice is to take a runner, which has rooted well at a joint, and, aftcr suitable pruning, to pot it for winter blooming and propagation.’ Others, again, take up the old roots, while others, by sinking pots in their verbena bed, about midsummer, allowed the runners to root directly PLANTS FOR WINDOW GARDENING. 51 in the pots; the pots being taken up, and the connection with the mother plant cut, the young plant receives no injury or check. But this mode is very objectionable, for two reasons: first, the loam in the pots is apt to become sour and sodden; and again, earthworms often enter the pots, and prove injurious during the aes The plants are housed, and, for a long time, produce no flowers, and are any thing but ornamental. Soon after the new year, they begin to grow vigorously, but are allowed to trail care- lessly over the staging, or droop from some hanging shelf. No care or attention is bestowed upon them, except to give the daily supply of water. The days grow towards spring. Cuttings are again taken off; the same process is repeated year after year ; and thus one of our loveliest flowers, which, with a little care, might be one of the greatest attractions and ornaments of our green-houses, is never seen in perfection, except in the garden. That this is the fact, is to be deplored; yet the remedy is simple. By beginning about midsummer, we may have verbenas in bloom as well during the winter as the spring months. About the first of August, or earlier, cuttings should be taken from desirable’varicties. In a fortnight 52 PLANTS FOR WINDOW GARDENING. they will be ready to transplant. Pot them in thumb pots, and re-pot as soon as the roots touch the sides of the pot. Keep them in vigorous growth by affording plenty of light and air, being careful they never suffer from want of water. Pinch off the leading shoots, to cause all axillary buds to break, and in no case allow them to bloom. Train the plant in any form desired, but be careful not to permit it to grow too straggling. When other plants are housed, remoye your verbenas to some warm shelf, where they may have the morning sun, and on every favorable day give plenty of air, and fumigate well to destroy green aphis. Your plants will soon be in luxuriant bloom, long before those potted in the common way have shown a bud, and will continue to afford an abundance of flowers until late in the spring. To grow verbenas well in the house in summer is far easier, They may be bloomed in pots of any size, and trained in almost any form, the only requisites being plenty of light and air, careful pruning, and means to destroy aphis and keep off mildew. 7 One great fault in growing verbenas is the-practice of watering too copiously. The plant, as originally found, grows on dry hills; and damp not only produces mildew, but rots the roots, and thus destroys or produces disease in the plant.

Many verbenas, which for green-house blooming are unsurpassed, are worthless for bedding purposes; the petal of the flower being too thin, or the color fading or changing. Again, some bloom well in winter, others far better in sum- mer ; some form large masses and flower well, others are of rambling growth and poor bloomers; some of creeping, others of more upright habit; while a few possess every desirable quality ; and in making a selection, all these prop- erties are to be considered. We have said that seedlings were produced with great ease. The verbena seeds well where the plants have not been too long propagated by cuttings. A long-continued propagation by cuttings seems to diminish the power of the plants to produce seed, and, as a general rule, the further removed a plant is from a seedling, the less the chance of its perfecting good seed. The seeds may be sown in a hot- bed or green-house, early in spring, and the plants, when about an inch and a half high, pricked out in the border; it is a good plan to pinch out the leading shoot, as thus the piants branch and become stronger; the plants grow rapidly, and soon show bloom. 54 PLANTS FOR WINDOW GARDENING. But to raise a seedling is one thing, to raise a fine seed- ling, a far different. Of many hundred raised in the course of the last few years, by the writer, not more than half a dozen have been worthy of preservation, and only one (and that produced by chance) really a first-class flower. In raising seed, much may be done to insure its quality by planting fine varieties together, and allowing them to intertwine, then gathering the seed from these plants. No rule can be laid down to obtain any desired color, for the seedlings sport infinitely. We can only approximate towards definite results; thus, if we plant Annie (white) and Robinson’s Defiance (red) together, the seedling will be likely to be pink. The flowers of the verbena are of every color and shade, except light blue, which color has never been obtained.
