Introductory
Practical Thanks. I know of no better expression of my appreciation of your business than to try to make my service consistently better and more helpful to you.
Time of Delivery. For seeds, any time; the earlier the better. All our plants are from outdoor stock, and digging can begin in March, continue through April, ending May 1st to May 15th. Orders for Lilacs and other plants that start early, should be placed in time for delivery before April 15th. It is an advantage to place all orders early; then, in making deliveries, we begin with California and the South, and reach the others all at the most favorable time. This helps to eliminate the rush near the end of the season and gives you better service.
Free Delivery. Plant orders with cash, amounting to $3.00 or more, exclusive of seeds, are delivered free. A delivery charge of 25 cents additional is required on orders less than $3.00 if wanted by mail. Evergreens and shrubs travel by express at purchaser’s expense, care being taken to avoid unnecessary weight.
Safe Delivery is guaranteed by parcel post or express. An immediate report of loss or damage with full particulars is required for adjustment.
Substitution. It is my policy to avoid substitution. Orders taken partly or entirely from an old catalogue are almost certain to include items temporarily out of stock. If you are obliged to use an old catalogue, please do not fail to include a few substitute items that may be used if necessary; otherwise in small matters I will substitute as closely as possible something of equal or better value.
Cannot Supply. If you have inquired for plant material or varieties not listed in the latest catalogue, and find this para¬ graph marked, please understand that such items are not available.
Canadian and Foreign correspondents who receive this cata¬ logue are requested to limit their orders to seeds, remitting cash in full with order.
Garden Clubs. The official of any garden club may apply for four copies of this catalogue for the use of members. These will be furnished so long as a supply is available.
Correspondence is invited with the Trade and with Landscape Architects, who are interested in our New or Noteworthy plants and shrubs.
Address all orders and correspondence to,

News of the Nursery
The other morning my thermometer stood at 28 degrees be¬ low zero. The official record for the night was 33 below. For seventeen days the reading has been zero or colder. This is unusual weather, but I thought you would like to know that our Rocky Mountain flowers are hardy; none hardier.
The mountains are a beautiful slight these crisp mornings. For a few moments at sunrise their snowy slopes are bathed with rose color. Although three miles away, each tree stands out with telescopic distinctness. Looking from the front door the shrubs in the nursery across the driveway stand up bravely in the snow. From the east windows a group of Juniper and Spruce is a reminder that Christmas is not far in the background, and that 1930 is still young enough for me to wish you all a happy and prosperous new year.
The photograph of the Rocky Mountain Bramble or Thimble- berry on the front cover reminds me that there are more than two thousand splendid young bushes in the nursery, ready to bloom next summer. I consider this one of the most beautiful and valuable shrubs that America has given to American gard¬ ens. I am proud to sponsor it. This block of bushes would not last long if each of you appreciated what a fine thing it is.
It is worth while to record that this lot of Mountain Bramble was grown in the nursery from seed. Almost everything that I offer is propagated now from seeds, cuttings or division; and this obviates any possible prejudice against collected plants. It insures a superior grade of stock, all fully acclimated to this altitude, which is 5,000 feet. As this is halfway in point of altitude between the subalpine zone and sealevel, the value of such acclimatization must be quite apparent, and the change to your garden from mine presents no difficulty.
“No difficulty,” because my chief endeavor in supplying high class novelties is to give the best of service in packing and delivery. Improvements which I have put into effect the last year or two have resulted in many unsolicited reports that are most gratifying.
The amount paid for postage is only part of the cost of delivery. Note the excellent material used in wrapping and for re¬ taining moisture without excessive weight or wetness. In order to continue and improve this service, including free delivery, it must be evident that each order must justify the cost of pack¬ ing and postage. Even trial orders should be large enough to permit a fair showing of my stock and service. This is the reason for announcing with this issue of the catalogue, that plant orders under $3.00 are not solicited. They are not entitled to free delivery.
I have seldom printed testimonials of any sort. The only thing that prompts me to do so now is the occasional expression of doubt that I can ship so far. My answer is, try it at my risk. But hear what others say. The complete letters are on file.
From New Jersey: “The plants came in splendid condition, the finest order I had this season. Very many thanks.” From Lincoln, Nebraska: “Received the plants, shrubs and bulbs of
2
D. M. ANDREWS, BOULDER, COLORADO
previous orders and all were in fine condition.” California: ‘‘Plants arrived last evening in wonderful condition. Am very much pleased with them.” New York: ‘‘Package of plants ar¬ rived yesterday in fine condition. Please accept thanks for liberal count.” Oregon: “The shipment of Lilacs came through in splendid shape, and the plants themselves “were a pleas¬ ant surprise. I particularly noted that the small sized ones were of good shape and with good roots and were well branched.” New York: “Plants arrived O. K. Thanks for such excellent service.”
Classified Lists
Plants for Special Purposes
In presenting lists of plants, classified as to use, it is with the caution that such lists are merely suggestive, and without the intention of limiting the use of the plants included; for ex¬ ample, plants that grow in dry places will usually grow equally well or better under ordinary conditions.
It is to be understood also, that most of the plants not included serve rather a general place in the garden or rock garden and that they are hardy to the north central and east¬ ern states, and that all except the newest introductions have a successful record both east and west. A soil of neutral re¬ action to mildly acid is to be considered favorable to success¬ ful culture, unless otherwise indicated. Items classified, but not included in the pricelist are temporarily unavailable. Please do not ask for detailed information by letter. Questions should be stated briefly, with space left for the answer, and a self- addressed, stamped envelope enclosed. I cannot undertake to answer questions otherwise.

Lovelier Lilacs
In the improvement of the old-fashioned lilac, a favorite from time immemorial, much credit is due French hybridists, par¬ ticularly the late Victor Lemoine of Nancy, France.
These superb creations are marked by both single and double flowers, individually of large size and produced in very ample clusters. Their wide range of color, delightful fragrance, last¬ ing texture and extended flowering season combine to increase the popularity of an old-time favorite.
The Secret of Lovelier Lilacs. There are two nursery meth¬ ods of propagating lilacs. One is to hud or graft on privet or other root stock; the other is by cuttings or layers to produce an own-root plant.
Lilac bushes growing and flowering on their own roots are conceded to be the best. They will remain always true to type, and cannot produce sprouts of a different kind. They are long- lived, have a perfect root system and bloom while very young. Years of satisfaction will many times repay your investment in this class of stock.
The advocates of budded or grafted lilacs claim first, more rapid propagation; this is granted. Second, that grafted bushes will soon become “own-rooted” if set deep enough to cover the union. Unfortunately, this does not often result.
If you wrant to buy grafted or budded lilacs — fine! But get it straight. If you are buying on the promise that they will become, sooner or later , own-rooted bushes, then you are trading on a narrow margin.
Study the picture showing root growth and decide for your¬ self. At the center are two own-root bushes (Charles Joly and Ludwig Spath) grown at Rockmont Nursery. Of the three bushes at the left, one is budded high up on privet, the others are probably grafted. I bought them three years ago; two are dead, the other has not bloomed. The two at the extreme right where from a wholesale nursery in Kansas, and were exactly as represented, grafted lilacs on privet roots. As is frequently the case, the top has overgrown the root and the plant will be short-lived.
Only one other comment seems necessary. It is only fair in referring to my own-root bushes, grown at Rockmont Nursery, to give due credit to my inimitable soil conditions, and second, to our mile-high climate where a dry atmosphere and intense sunlight compel lilacs, in common with all other nursery stock, to produce an amazing growth of fibrous roots.
After many experimental purchases I am satisfied that nothing offered anywhere can surpass this Rockmont stock for a “quick pickup and getaway.” Some of my customers have re¬ ported blooms the first season; and almost invariably they become established and flower freely the second year.
Culture. — Lilacs like sun and air, require plenty of moisture with rather free drainage. They will repay good care, yet often give splendid results under seeming neglect. In land of moderate fertility freedom of bloom is likely to increase with the age of

the plant, and with plenty of room very little pruning is re¬ quired; in any case avoid cutting the ends of strong branches which would sacrifice flower buds.
The size of bushes will average two to three feet tall, unless otherwise indicated. ‘‘Small plants” will be less than two feet hut well established stock. “Large bushes” are three to four feet tall or larger, and are exceptionally fine stock and heavily rooted.
Not prepaid. Lilacs must be shipped by express. Excessive weight is avoided in packing to insure economical transporta¬ tion. Lilacs should be delivered in spring before growth com¬ mences. Place your order early enough for shipment before April 15th. Autumn delivery begins about October 20th and continues through November.

New or Noteworthy Shrubs
Including Miniature Shrubs
It is possible now to put an entirely new accent into your planting effects by making a free use of western native shrubs from the highlands and valleys of the central Rocky Mountains. These shrubs are hardy to South Dakota, Michigan and the colder parts of New England, and except as specifically stated, will thrive under ordinary garden conditions. A few, recom¬ mended for dry conditions, should not be subjected to an excess of moisture or poor drainage.
Most of the following list are native shrubs. A few, equally hardy, are included from other sources. It should be noted, in the case of shrubs which have a wide range of distribution to the southward, or westward, that the Colorado form always
SHRUBS 7
excels in hardiness. The size indicated following the name is the approximate size at maturity.
The stock offered is nursery-grown, and well rooted. Where no size is indicated, a 2-year grade, about 2-3 feet in height, is to be understood. Small, indicates two feet or less; large, 3-4 feet or more. This system of grading does not apply to “Miniature Shrubs” although corresponding in age.

*Yucca coloma, Soaproot. Best of all the yuccas for the rock garden because of its small size, it is proving to be in the East a most satisfactory grower, originating as it does in a climate of more abundant rainfall than the desert types.

Peonies, Iris and Phlox
Rockmont Introductions
During the reconstruction of nursery affairs in my change from a general nursery to one of specialties, it became necessary to omit my fall lists of Peonies. Now that the reorganization is pretty well an accomplished fact, I plan a midsummer catalogue that will give more adequate attention to the three flower groups named above.
I may say too, that stock of the outstanding varieties has been propagated consistently and that the present quantities justify a material reduction over the introductory prices of those previously listed. And also, that sufficient stocks are available of a few new things in Peonies to permit their introduction at attractively low prices.
Just to forecast some of the splendid offerings in Peonies I will announce for fall delivery the following revised prices: Manitou, late, heavy-stemmed shell-pink, 05. 00; Nimbus, tall, stiff-stemmed late cut-flower huff-white, 07.50; Sixty-six, a valuable free-blooming fragrant red, color of Filix Crousse, but of stronger habit, 05.00. Then there is a marvel in deep rose and most brilliant yellow, the center intermingled or all yellow, very full and a heavy flower, profuse bloomer with a stout stem; the name is Rosaureo; price to be given later. The largest full double peony I have ever seen is number (17-34). Young plants bloom regularly and the massive deep pink blossoms open freely with none of the tightness common to large-flowered va¬ rieties. The person proposing an appropriate and acceptable name, personal names excluded, will he awarded a root of this variety free. Number (20-08) is an erect-growing intense red, nearly as deep as M. Martin Cahuzac, hut much brighter with a warm tone.
From my Japanese Peony seedlings I shall select six, in¬ cluding two new ones. Silver Plume is very large and its center
20 D. M. ANDREWS, BOULDER, COLORADO
is larger, fuller and more feathery than any other I know, not excepting Ama-no-sode or Tamate-Boku. The color of the very narrow twisted filaments is silvery pink, they are as long as the guards and fill the center like a bomb-type peony. Whether you care for Japs or not you will love Silver Plume. Number (2020) is a seedling of Mikado, but is several shades darker, a plant of finer habit, very erect. The center is of dark red ligules of even length, the tips encrusted with gold. Prices will be given in the summer catalogue, and revised prices on Calypso, Fla¬ mingo, Rosebud and Shavano.
Iris Introductions for spring delivery are priced as follows. Prices for summer delivery are expected to be shaded a little lower if stocks will permit.
Alabaster, purest white, price each _ 3 4.00
Amerind, tall golden bronze _ 4.00
Candlelight, rosy mauve and gold _ 7.50
Jacksore, vinous red self _ 10.00
Odaroloc, rose-toned lavender _ 1.50
Ophir Gold, very late, pure yellow - , - 1.00
Phlox Introductions. The six varieties of Phlox offered below include four exceptionally brilliant bits of color. The four are Mendelian hybrids derived from Coquelicot, into which larger size has been introduced, together with greatly improved habit and constitution. Osceola, Snowcap and Tanager have florets larger than a silver dollar, Silverton much larger, and Colorado approaches closely. Robin Hood is of medium size but larger than others of its color class. All were new last season, except Silverton, which was introduced in 1927. One root each of the six for §10.00 delivered, prepaid.
The prices are for strong field-grown roots, sold singly as follows:
Colorado _ §2.00
Osceola _ _ 2.00
Robin Hood _ 2.00
Silverton _ _ 1.25
Snowcap _ _ 1.50
Tanager _ _ 2.00
Seeds of Shrubs and Rare Specialties
Owing to the longer time required for the germination of most shrubs, it is thought best to offer in packets of stated quantity which will be of practical value for commercial growers. Therefore, the offerings are the smallest quantity sold; no small packets.
A few very choice specialties are included in this list while our supply lasts at the prices quoted. Please order early, before April 1st if possible. I will refund if sold out.

These seeds of the glaucus Blue Spruce are from a high isolated valley where the trees are all very blue, no trees that would be classed as green. The run of the valley, (glauca X) will reproduce nearly 100% blue, as I have proven from seedlings already grown to character size. The grade (glauca XX) was saved from a single group in this valley, every tree of which was as blue as a grafted Koster spruce. I have taken seedling trees from this spot that are bluer and retain the color better with age than Koster trees when grown side by side in the nursery. I am reserving part of this (glauca XX) for my own planting, but have a few pounds to spare, not more than one pound to a customer.

General List of Seeds
The germination period of seeds of perennials varies from a few days or weeks to several months. There is a prevailing notion that fresh seeds germinate quickly, or more quickly than seeds a few months to a year old. Of the kinds here listed, with possibly a few exceptions, there is no difference what¬ ever. If seeds ofClematis Texensis be planted the same day they are gathered, they would lie dormant one full year from the following spring, some 18 months in all. No coaxing or persuasion will hurry it. Each kind of seed has its minimum period which is often prolonged by unfavorable conditions.
Unless you possess a good degree of patience, the use of plants already advanced to the flowering stage, will save time. Excellent reports come in telling of success with my seeds, and quite a number of the following items are not yet available as plants.
Warranty. I supply seeds which I believe to be of sound quality and able to germinate under proper conditions. They are sold at a nominal price. Successful culture depends upon con¬ ditions not under my control. Upon these considerations, please do not ask for replacement or reimbursement in case of failure.
