A narrow leafed version of the classic Hart's Tongue fern from Europe.  We've seen the typical species happily growing in English hedgerows and closer to home, naturalizing on a shaded mossy brick wall at June Sinclair's garden.  This form is quite striking with it's stiff, evergreen lance-shaped leaves and would be well suited to an artist's garden.

Maidenhair Spleenwort.  I love common names.  I must dig out our 15th century Herbal and read up on how to properly decoct this sweet little fern for afflicting humors of the spleen.  Or I can just grow it in a gritty well-drained shaded rock garden and enjoy its evergreen delicacy.
