Guide

The species-level account. Cultivar pages build on this and say where they differ.

Asplenium trichomanes is the maidenhair spleenwort, a small fern that grows on rocks and crevices across temperate East Asia, where its roots cling to gritty, fast-draining surfaces rather than sitting in soil. It wants a sharply drained, mineral mix and steady moisture without saturation; water when the top of the mix is approaching dry but before it fully dries out, and never leave the crown standing wet. As a lithophyte from cool, shaded, humid niches it prefers indirect light, good airflow, and elevated humidity.
