Appearance
''A. villosa'' is very variable. The typical form grown in gardens is a small tufted or mat-forming perennial, with rosettes of linear to elliptical leaves, up to 1.5 cm across. The leaves have fine hairs underneath, particularly towards the tips. The flowers, which are 6–10 mm in diameter, are in umbels on stems up to 3 cm tall. They vary in colour from white to red-purple, with a pink or yellow eye. The white forms may age to pink.
Distribution
In the wild, ''A. villosa'' grows on limestone mountains in Europe and Asia, usually on rocky slopes above 1500 m.References:
