FERNS

This issue of the newsletter features ferns as a reminder of the upcoming Fern Sale.

Wednesday, June 19th 10:30 AM - 3 PM Arboretum

Definition of a fern. A member of the order known as Filices: non-flowering, rather primitive perennial plants

whose green parts are referred to as fronds and which multiply by spores, not seeds.

The word fern relates back to the Sanskrit word parnam meaning feather. The letter "p" was probably given an "f" sound and by the time it went through the changes from Greek on up through Anglo Saxon it became the word "fern” in Modern English.

ABOUT THAT BRACKEN!

However we may look or not look a+ pteridium aquilinum (bracken fern) today, it is historically credited with some wondrous economic, medicinal and supernatural values.

Throughout the world, where it is indeed endemic, parts of it have been roasted,

pounded, boiled, brewed in ale and otherwise prepared as food. My search

yields no gourmet recipes, however. It appears that at best it can be made palatable.

Medicinally it was reputed to cure sores of all sorts as well as nose bleeds and was especially recommended as a bath "to restore the strength of the sinews." Prescrip¬ tion: one basket chopped fern per 84 gallons of hot water.

The most elaborate folklore associated with the bracken concerns the power of its "seed" to bestow the gift of invisibility. Long before scientists discovered the reproductive cycle of the tern, they were faced with this peculiar order of plants that had no flower, no seed and yet was obviously capable of reproducing itself.

Logic combined with legend supposed that the fern produced an invisible seed which while useful for multiplying the fern was especially treasured for the magical powers given to anyone who possessed the seed. Great rituals and one assumes not a few capers evolved in pursuit of the seed. While varying from region to region the predominating belief required that the seed be caught precisely at midnight on Midsummer Night’s Eve. This pursuit lasted well into the 19th century although it had been outlawed as early as 1612 by the French as a form of witchcraft. While Shakespeare apparently believed, he allowed for at least one skeptic in Chamberlain of Henry IV who remarked to GadshMI, "You are more indebted to the night than to fern-seed for walking invisible."

Bracken which when dry is indeed highly flammable was burned annually in many parts of the British Isles, its alkaline residue being used for soap and glassmaking.

This burning of the fern, western Washingtonians take note, was also supposed to bring on rain, a matter taken so seriously that Pembroke wrote to the High Sheriff of Staf fordsh i re prior to a planned visit by King Charles I specifically asking that they refrain from the burning so that the King could enjoy fair weather during his stay.

Finally, while this just briefly touches upon the wonderful or awesome aspects of bracken, I do think it should be known that sleeping on a bed of bracken will keep the fleas away!

STAGHORN FERNS

The genus Ptaty oer*ium , commonly called Staghorn or Elkhorn ferns, may be considered to be among the most distinctive and most beautiful of ferns. There are seventeen species and many cultivars of garden origin and they range from tropical Africa, Asia, Australia, to South America. Their respective sizes range from the 12 inch P. madagascaviense to P. Wilhelminae-Reginae which can be over 6 feet in diameter. All are ep i ph i t i c.

The Staghorn ferns are distinguished by their d i chotomous I y forked fertile fronds which bear sporangia at the extremeties of the fronds on the under side. The fertile fronds appear to grow from the shield fronds which are green when young, then turn brown at maturity. These shield fronds must be left attached to the plant to prevent rot of the crown of fertile fronds. In their native habitats. Staghorn ferns grow in trees and occasionally on rocks, on which the shield fronds grow flat against the support and function to collect organic material behind them which decays to nourish the roots.

In cultivation, Platy ceriums can be grown in pots, wire baskets, mounted on rough sawn cedar or redwood lumber, or in the fork of a tree branch, being sure to allow for several years growth. A good potting mix to use consists of 1 part leaf mold, 1 part planter mix, and 2 parts shredded bark (a coarse grade of orchid bark) or a coarse grade of peat moss. The plants should be soaked thoroughly after planting and then not watered again until they start to droop and then a regular schedule of watering should be maintained. Fertilizing can be done at 2 month intervals, alternating between weak solutions of several organic fertilizers like Spoonit, blood meal, fish, and some commercial dry forms; watering well after each applica¬ tion .

With the exception of P. bifurcation and many of its forms which can be grown out¬ doors in a shady position during the summer, Staghorns are greenhouse plants and should be grown between 60 and 85 degrees with high humidity and good air circula¬ tion. All must be given winter protection. Height and lots of space should be allowed to grow specimen plants.

Propagation is generally done by means of spores which may take up to two years to germinate, or by removal and potting up of offshoots. Platyceriums are slow growers, but their individuality and beauty make them well worth the effort.

FAVORITE FERNS:

Pityrograrma triangularis var. pallida (Syn. Gymnogramma triangularis) . I hope I shall be forgiven for choosing a fern virtually impossible to obtain, obstinately persnickety to grow once you do obtain it. But favorite is favorite, and mine is the silverback fern, Pityro gramma triangularis var. pallida (Syn. Gymnogramma triangularis) , from central California. It is an elegant beauty, a variety of the ubiquitous gold-back fern Pityrograrma triangularis found from southern British Columbia to southern California. Both are horrendous to tame and indeed we manage them here only as pot plants bone dry in winter, hardly less so at other times of year.

Pityrogramma is a densely tufted fern, about 5-10 inches high, with pinnate leaves on a dark brown glossy stem, the fronds deep green above, white with a waxy powder below. If it is kept dry, the entire plant exudes this silveriness like some miniature ornamentation of the Age of Elegance. The fronds are pentagonal in shape, partly or twice pinnate; the two basal pinnae are large and deeply lobed. The black sori are almost invisible because of the powder. There is no indusium.

In nature I understand it inhabits xerotic rock crevices. In summer it goes dormant because of the lack of moisture and shrivels up to a brown nothing. It is not wise to treat the plant this way in cultivation from the point of view of either aesthetics or the health of the plant. It needs water in summer, not much, but enough to keep it green - I should say silver.

Last year we collected spore from our plant and seasoned fern growers have germinated them and will hopefully keep them going. Growing such a temperamental beauty is always problematical so one would be reluctant to offer too much dogma: err on the side of drought; avoid too much frost - even though this is a mountain plant it is still California; give it a gritty, open, compost; cherish and love, for there are few such beauties (to my mind) in the entire plant kingdom.

Polystiohum setiferum is my choice, largely from practical considerations, but it is also high on my list of ferns for beauty and variety. Recent winters have generated a greater appreciation for cold hardiness in ferns, and most varieties seem to be nearly as hardy as our native species. General adaptability is good also, with the most common forms being as easy to grow as P. munitum. Light to medium shade, reasonable drainage, and some nourishment to get established are the main demands.

There are dozens of varieties in existence, and there have been hundreds. The number has been reduced by grouping similar forms and by actual losses during the war years in England, the primary source in the wild and in cultivation. My own experience involves only about nine forms, most of them not identified, unfortunately.

P. setiferum oongestum3 an'd its crested form var. grandiaeps are compact varieties, 10-12 inches in height, which are good ferns for the rock garden. These are not as hardy as the larger varieties and about half of them in my gardens were killed during the past w i nter.

The most common form available in the nursery trade, vav. 'proliferum1 3 is very adaptable and can be readily propagated by the piantlets which form along the rachis. It has somehow picked up the erroneous name 'Alaska fern' which is misleading because it has no connection with Alaska. Another nomenc I atura i problem involves confusion between P. setiferum and P. aeuleatum. As far as I know, all the more commonly avail¬ able varieties are in the former. Though these two species are genetically distinct, with different chromosome numbers, they are so similar in description that I doubt if most of us could differentiate between them.

James Baggett, Corvallis, Oregon

Adi antum pe datum "Carl English's Form". This might not be the proper designation for my favorite fern but it tells exactly what plant i mean; no other five-finger maidenhair is anything like it. In shade this reduced version of the common and widespread A. pedatum is lush and "fluffy" in the proper manner, with all the delight of the type in te I escoped-fash i on - total stem length is much reduced as are the internode distances so that each of the leaflets is partially overlapped by, and partially in turn, overlaps adjacent ones (in a way called "imbricate"); in the sun¬ shine the size of leaflets is also much reduced and the color is more "bluish" (glaucous). Thus it may seem to be "different" according to where and how it grows, from 3 or 4 to 8 or so inches in height and slowly (or quite quickly, when in a rich moist soil) forming clumps of a kind of beauty that is so "ferny".

The story goes that Carl English brought this from an island offshore in the Strait of Juan de Fuca and propagated it by vegetative division and by spores. It remains quite fixed in its unique, reduced way and certainly is to be considered one of the choicest of ferns for gardens, and of course, especially for small gardens.

Roy Davidson, Bellevue, Washington

Asplenium triohomanes (Maidenhair Spleenwort) is one of my favorite ferns because of its exquisite beauty and ease of culture. A small rock garden fern, its dainty evergreen fronds 5-8 inches, are seen best surrounded by a foil of moss. An adapt¬ able fern, I also use it in containers where it can be seen close-up and make a perfect companion for the very dwarf flowering plants. It is a native of our Pacific Northwest usually found on rocks in moist conditions. Give it much shade and never let its roots dry out. Another good way to grow it is tucked between two rocks.

Dryopteris erythrosora, one of my favorite ferns, is most distinctive and striking with its wide shining dark green fronds. The young new fronds are reddish copper until they mature, while the indusia protecting the sori is red. It is hardy here at 400 feet in the foothills of the Cascade Mountains and remains evergreen through the winter. As it is one of the most decorative ferns for our gardens, it is fortunate that it can be easily propagated from spores.

Polystiohum lonohitis , the Holly-fern, native of North America and Great Britain, is usually found in the mountains on rocky slopes in protected crevices among the rocks. There are several narrow ascending glossy fronds with the many pinnae closely crowded on the stems. It is a difficult plant to transplant when collected in the wild, so it is better to raise it from spores. When grown in gritty humus it makes a most pleasing plant for the garden.

Bleohnum penna marina. As an avid gardener I am especially interested in the wee bits of plants suitable for either sunny or shady parts of the rock garden (or at least plants of rock garden stature). If the truth were known I think that every member of the genus Pellaea is my favorite. However since the pellaeas come predomi nent I y from hot limestone crevices, they are extremely difficult to cultivate in our northwest gardens.

For this reason a gem from the high mountains of New Zealand, Bleohnum penna marina comes to mind as a completely satisfactory easy going fern for many areas of the garden whether you’re an alpine specialist or not. This truly is one of my favorite dwarf ferns.

Roughly speaking Bleohnum penna marina looks much like a pocket edition of our native deer fern B. spioant. The sterile fronds form neat little rosettes close to the ground; the more exposure and the poorer the soil the shorter the frond (H ~

2 inches long). The fertile fronds are somewhat longer and grow straight upward.

When we first became acquainted with this little jewel of the southern hemisphere, we were doubtful about its hardiness. However after nearly 15 years experience of growing it without winter protection we have learned that it will withstand what¬ ever our Pacific Northwest climate has to offer, even prolonged 8°F with and without snow protection.

The plant spreads by stolons forming new little rosettes as it creeps about.

During the winter some of the fronds brown off but in spring the new growth is a delightful pinkish copper. When grown in the shade the plant is larger in all its parts. It can successfully be used as a ground cover beneath medium to large rho¬ dodendrons where the foliage textures afford a pleasing combination.

PROPAGATING FERNS FROM SPORE:

Ferns come readily from spore under fluorescent lights. The light unit should be located about eighteen inches above the propagating medium, and should be operated about twelve or fourteen hours per day. If fluorescent lights are not available the container may be set in strong light, but not in direct sunlight.

Any transparent container may be used but the trans¬ parent plastic shoe boxes seem to be the most practical. Each box will hold eight or ten small flower pots. Any well drained potting soil may be used in the bottom of the pots, and then covered with half an inch of peat

Propaga ti on Cul ti vation

moss and sand, broken up clay pots, or most any other sterile mixture. When using sterile mixtures as the propagating medium, there does not seem to be any advantage in sterilizing the material. Do not plant spore directly into a soil mixture, as algae will grow and smother the young sporlings.

The spore which is very minute, should be planted, sparingly, on the moist surface of the medium. Place a i inch of water, no more, in the box and then cover with a transparent lid or saran wrap. This cover can remain on the box until the sporlings are ready to transplant.

Spore ripens from late spring through to late fall depending on the genera. The sporangia (spore receptacle) will generally be shiny and dark when the spore is ripe. If the sporangia is dull tan, the spore has probably been disbursed. The ferti le frond may be cut and placed in an envelope, and after a few days you wi I I find a fine dust in the bottom of the envelope. This is the spore.

CULTURE:

Nei I i Hall, Seattle, Washington

Although most ferns prefer moist soils with plenty of humus and some shade, there are many that prefer sun and dry conditions. However all ferns grown in gardens respond to some feeding. I give mine a half strength solution of liquid fish fertilizer which noticeably improves their appearance and well being. Two feedings, six weeks apart in the early spring while they are in active growth seems to be sufficient. All fertilizers should be kept off the fronds and the crown of the ferns
