Ecology

A short, tufted perennial herb, usually found on base-rich substrates and less frequently in acidic conditions. It grows on wet rocks, consolidated screes, in grassland and in damp flushes in the mountains, and it is often abundant in montane pastures. Reproduction is mostly by bulbils at the base of the inflorescence, frequently carried down to lower levels by streams. It reaches 1210 m on Ben Lawers (Mid Perth), but descends to near sea level in N. Scotland.
