Description

Trifolium andersonii is a perennial herb growing in a tuft or low cushion, and lacking a stem. The long-haired or woolly, silvery-gray leaves have 3 to 7 leaflets each up to 2 centimeters long. The inflorescence is a head of flowers measuring 1.5 to 2.5 centimeters wide. Each flower has a calyx of sepals with narrow, densely hairy lobes. Within the calyx is the flower corolla, which is pinkish purple or bicolored.

Various subtaxa are usually recognized by authors as varieties or subspecies.
