Adiantum and Other Ferns

adiantumpedatum (2) (300x295)Adiantum pedatum – Eastern Maidenhair Fern is an RHS Award of Garden Merit winner featuring delicate-looking pale green fronds held on black stems. It prefers part to full shade with even soil moisture (it does poorly in dry conditions). This species is herbaceous and over time forms large clumps. Beautiful container specimen. Grows 12-20″ high by 16-24″ wide. Zone 3.

adiantumhispidulum (293x300)Adiantum hispidulum – Rosy Maidenhair Fern is native to Australia and New Zealand and features distinct rosy-pink toned new growth (more pronounced with a little sun). It is herbaceous in zones 7 to 8 but is easily grown as an evergreen houseplant in colder regions, which is why I frequently find it in mixed flats of unnamed indoor ferns. Grows 10-18″ high by 15-18″. Zone 7-8.

adiantumvenustum (2) (300x298)Adiantum venustum – Himalayan Maidenhair Fern is an herbaceous species that is evergreen in warmer regions. It features very finely-cut fronds of bright green borne on contrasting black stems, with bronze-pink new growth. This RHS Award of Garden Merit winner is native to China and spreads by creeping rhizomes. Grows 6-12″ high with indefinite spread. Z5.

9-12-2011 17-44-42_025 (300x269)Asplenium ebenoides (syn. Asplenium x ebenoides, Aplenosorus x ebenoides) – Dragon’s Tail Fern is a natural hybrid of Asplenium rhizophyllum and A. platyneuron that is native to eastern North America. It is reliably evergreen and generally grows on rock outcroppings, featuring thin dark green fronds held on black stems. Grows 6 to 8″ high by 8 to 12″ wide. Hardy to zone 5.

9-12-2011 17-0-15_002 (291x300)Osmunda regalis – Royal fern is an RHS Award of Garden Merit winner and a very worthy specimen plant for the bog garden with its Robinia-like green fronds. The spores are carried in brown terminal clusters (above the foliage) and add to the overall appeal. Older specimens develop an elevated bristly root crown. Grows 3-4′ high (taller with moist conditions) by 2-3′ wide. Zone 3.
