Pteris wallichiana

This was one of those "Holy shit - lookit that fern!" moments when we first spotted this species growing in a moist stable and vegetated scree at the base of a soaring vertical cliff face fronting this mountainous outcrop of improbable pinnacles in Guizhou, China, The fern was perfect in scale and not intimidated in the slightest with 5'-6' wide leaves on a clumping plant 6'-8' tall. We were dismayed not to collect spore but happy to get a small plant of this species from fernologist Sue Olsen a few years back. This grows to be a pretty hefty clump but does not run. Hardy to zone 8 and mulch crown if it gets serious in winter.
