Description
The plant has stems growing 10–30 cm tall and bear single, white (rarely pale pink or pale bluish) flowers two centimetres in diameter, with five to nine (most often six) elliptical tepals. The fruit is a cluster of 2 mm achenes. Its leaves are divided into three lanceolate leaflets and form a single whorl of three leaves per stem; the leaflets have a toothed but not lobed margin. The rhizome, found directly below the surface is whitish, and tends to form dense clonal colonies.[2][3][4] In subsp. albida, the achenes are pendulous.[3] The flowering period extends from April through June.

It occurs in hardwood forests and rocky sites up to 1860 metres of altitude.[2]
Subspecies
The Portuguese and Spanish populations are distinguished as A. trifolia subsp. albida, with the remaining populations being A. trifolia subsp. trifolia.[5]
