Asplenium balearicum

Balearic spleenwort

A small evergreen Mediterranean spleenwort of shaded coastal rock crevices in the Balearic Islands, Corsica, Sardinia, Sicily, southern France and Tunisia. It grows in the mild, wet winter and survives the hot, dry summer in shaded, humid clefts. In cultivation it needs a cool, bright-shaded, well-drained setting with drier summers.
