Description

edit

Potentilla tilingii is a perennial herb forming tufts of erect leaves and stems. The leaves are 3 to 12 centimeters long, each made up of hairy gray-green leaflets which are tipped with usually three teeth. Unlike many other horkelias, this species is generally not strongly scented. The green or reddish stems reach a maximum length of about 40 centimeters and hold clusters of flowers. Each flower has minute bractlets beneath small, hairy, pointed sepals and narrow white petals.
