Asplenium sagittatum
A small Mediterranean fern with arrow-shaped, undivided fronds, formerly called Phyllitis sagittata. It grows in shaded, humid crevices of limestone cliffs, sea caves and gorges, and on the walls of wells and irrigation shafts, mainly near the coast. Grow it cool, shaded and humid on a limy, free-draining mix, and let it slow down in a warm summer.
Where it grows wild
