Tongue Fern


Add to wishlist Remove from wishlist
Tongue Ferns are widespread in China and Japan where they can be epiphytic as well as lithophytic on rocks. Fantastic variants are being selected by the cult followers of Pyrrosia in Japan and "Tachiba Koryu' is one with evergreen blade-like leaves sporting rounded lobes along the margins. Does fantastic at Peckerwood Gardens near Houston. We have seen the species making impressive colonies on rock faces or in mossy rubble during various China forays and it is always like coming across an old friend in the forest. This is best grown in loose, well drained soil and would be happy in a rotting stump or lightly shaded scree bed.
