Asplenium creticum

A dwarf spleenwort endemic to the high limestone mountains of Crete (Lefka Ori and Dikti), where it grows in rock crevices at 1700–2200 m, sometimes alongside Asplenium aegaeum, A. ruta-muraria and A. trichomanes subsp. quadrivalens. It is listed as Vulnerable and threatened by over-collecting. In cultivation it needs an alpine-house regime: cold, snowy winters and dry, sunny summers with roots kept cool in rock.

Where it grows wild

Crevices in limestone cliffs and rocks in the high mountains. The crevice holds moisture and shades the roots through the dry summer.

Recorded at 1700–2200 m; the measured site is at about 2340 m.
