Asplenium ruprechtii

Asian walking fern

The Asian walking fern, formerly Camptosorus sibiricus. Small, evergreen, undivided triangular fronds taper to long thin tips that root where they touch the ground, so a colony walks across moss-covered rock. It grows on shaded limestone ledges and lime-rich forest rocks from Siberia and Mongolia to Korea, Japan and northern China, and is fully hardy. It is the Asian counterpart of the American A. rhizophyllum, told apart by its wedge-shaped frond bases.
