Asplenium aegaeum

The Aegean spleenwort, a small rock fern of limestone crevices described in 1973 from the Aegean region. It is known from Crete, other Greek islands and mountains, and western Turkey. It lives in deep, shaded or north-facing cracks in limestone, from the lowlands to high mountains on Crete. It needs a winter-wet, summer-dry Mediterranean rhythm, excellent drainage and alkaline rock.

Where it grows wild

It grows as a chasmophyte in crevices of limestone cliffs and rocks, usually in partly shaded, sheltered cracks where the roots stay cool.

The measured sites are at about 375 m on the Greek mainland and 2030 m on the Cretan mountains, which suggests a wide elevation range.
