Asplenium chasmophilum

Asplenium ×chasmophilum is a hybrid spleenwort from the Canary Islands, named by Van den Heede and Viane in 2002. Its name means 'crevice-loving'. Grow it like other Canarian crevice spleenworts: mild, bright shade, sharp drainage and a drier summer.

Where it grows wild

No habitat notes were reachable. The epithet points to rock crevices, and Canarian spleenworts grow on shaded cliffs and ravine walls in the laurel forest and cloud belt.

There are no records. The climate point sits at sea level; the plant probably grows higher, in the humid mid-elevation belt.
