Fern Terminology “The bright colors of flowers are admired by the lest intellectual, but the beauty of form and textures of ferns requires a higher degree of mental perception and more intellect for its proper appreciation.” - Abraham Stansfield, 1858. FERNS 2010 Sold out until fall ADIANTUM HISPIDULUM: This is the montane Hawaiian form with beautiful soft red broad new pedate fronds. Survived to 24ºF in an unheated greenhouse and to 15ºF outdoors (barely) 12/08. Deciduous. Zones 8-11 or with humidity and no drafts - indoors. 12”. Limit 1.. 10.00 ADIANTUM × MAIRISII: is an interesting lacy old (pre-1885) deciduous maidenhair hybrid between Adiantum capillus-veneris, which it resembles, and an unknown. (DNA analysis welcome.) Spreads slowly in humusy soil in the garden or container. Zones 8 to 10. 15”. Rare. 8.00 ADIANTUM VENUSTUM: Himalayan maidenhair: My parent plant has received more compliments than any other fern in the garden while steadfastly resisting spore propagation. After years of experimentation it has finally come from tissue culture and I’m extremely pleased to add it to our offerings. It is an evergreen with pink tinged new growth unfurling early (March here). It creeps gently, never invasively, forming a frothy carpet in light shade and makes a handsome underplanting for studier shade lovers. Triangular 12” fronds. Zone 5-8 12.00 ASPLENIUM TRICHOMANES: The maidenhair spleenwort is an exceptional evergreen for the foreground in either partial shade or partial sun with a preference for rock gardens and good drainage. It is a wee evergreen growing to 8” more or less depending on the garden placement. One of the easiest of the aspleniums (and one of the few that are slug resistant) it is found in rocky crevices worldwide and the mortared walls of historic buildings in the UK and Europe. Adaptable Zones 3 to 9. 12.00 ASPLENIUM TRICHOMANES ‘INCISUM’: Finely cut fronds decorate this 8” evergreen. Great foreground subject in partial shade to partial sun. Zones 3 to 9. 10.00 ASTROLEPIS SINUATA: (Syn. Cheilanthes sinuata): Wavy cloak fern is living proof that not all ferns are shady woodlanders. This pinnate xeric is “cloaked” with white curly hairs on the fronds’ undersides and is a showstopper in our garden. It needs bright light, gritty, good draining soil and protection from winter wet. I grow it under the eaves facing south with filtered summer sunlight. Evergreen 15”. ZoneS 7-10. 8.00 ATHYRIUM NIPONICUM ‘PICTUM’ – REGAL RED: This is my favorite of the many named selections of the “painted fern”. Pastel silvery 10” deciduous fronds are swirled with wine colored accents. The contrast improves with age. Best in filtered shade with no direct sun. Zones 4-9. 8.00 ATHYRIUM OTOPHORUM: Auriculate lady fern: This is a colorful delight of Japanese origin with light green bipinnate fronds and a dark wine hue spreading onto the foliage from the rachis. New growth is the color of lime sherbet and displays well when surrounded with dark greens. Eastern customers (Zone 6) recommend spring planting. Semi-evergreen in mild winters here, usually deciduous. 2’. Zone 5-9. 8.00 CHEILANTHES WRIGHTII: From the American southwest, this fast growing, evergreen 8” xeric with bluish foliage is easier than most. Good drainage, sun and protection from winter wet help. Zones (6?) 7-10 8.00 CYRTOMIUM CARYOTIDEUM: Upright once-pinnate evergreen with angular light green foliage which contrasts splendidly with feathery woodlanders. Can take deep shade. Indoors or out. 2’. Zones 7-10. 8.00 CYRTOMIUM FALCATUM ‘BUTTERFIELDII’: A polished rich green striking evergreen suitable for indoors or out. Stiff teeth outline the pinnae. Excellent foil with soft perennials in shade. 18”. Zones 7-10. 9.00 CYRTOMIUM FORTUNEI VAR. INTERMEDIUM: Beautiful matte, yellow green, once pinnate holly-like foliar highlight in the company of dark lacy foliage. Reputed to be the hardiest of the holly ferns. Evergreen 12”+ horizontal fronds. Also easy indoors. Zones 5-10. A best seller. 8.00 CYRTOMIUM MACROPHYLLUM: Large leafed holly fern with pale green, broad, tulip shaped pinnae. Nice foliar contrast among deep green shrubs and ground covers or in the company of yellow and green variegated hostas. Evergreen. 2”. Zone 6-10. Unfernlike architecture. 8.00 DOODIA CAUDATA: This attractive rich green evergreen from “down under” emerges in shades of rosy red and retains the red as a brilliant stipe. Fast growing to 12”. Drought tolerant. Zones 8-10. 8.00 DRYOPTERIS CHAMPIONII: is an elegant evergreen with silvery new (but late) spring growth. Fronds mature with an open structure of shiny green and hold well through snow. 2-3’ Zones 5-8. 8.00 DRYOPTERIS LEPIDOPODA: Sunset fern: This handsome coral, orange and gold Himalayan resembles D. wallichiana in outline but is enhanced with warmer sunset hues in new growth. It looks superb with yellow flowered primulas and the feathery flowers and spring foliage of epimediums. A favorite, sturdy bipinnate evergreen. 2’. Zone 6-9. 9.00 DRYOPTERIS MONTICOLA: A D. goldiana twin and considered by some to be a subspecies thereof, this pastel green 2-3‘ deciduous fern comes to us from well-chilled terrain in Siberia, Japan and China. Zones 3-8. Limit 1. 9.00 DRYOPTERIS PULCHERRIMA: This is a distant cousin of D. wallichiana and shares the sturdy leathery frond characteristics. New introduction from the high Himalayas. 2’+. Evergreen. Zones 6-9. 9.00 DRYOPTERIS SIEBOLDII: Striking unfernlike bluish 2-3’ evergreen upright fronds. Bushiest in heat. Stunning anywhere. Zones 6-9. 9.00 DRYOPTERIS X COMPLEXA: (D. affinis × D. filix-mas) ‘ROBUST’: Bold 3-4’ vigorous evergreen bipinnate fronds give this fern massive substance. Once established it is remarkably drought tolerant. Great for screening. A best seller. Golden scales on new growth. Zone 4-9. 8.00 GYMNOCARPIUM OYAMENSIS: A lovely slowly spreading ground cover with stiff upright stipes and soft horizontal foliage that lightens the shady and slightly moist woodland. Deciduous. 12”. Zones 7-9. 7.00 PELLAEA ROTUNDIFOLIA: Button fern and cute as a button it is. Note, however that like its xeric relatives it suffers from over watering. Bright green dense “button” foliage. Evergreen. 15”. Zones(8?)-10. 8.00 POLYPODIUM SCOULERI: Glossy evergreen fronds highlight this slowly spreading shade lover from the Pacific coast.
