The leaves are edible, raw or cooked, and the flowers are edible raw, but not considered good to taste. Woolly geranium was used by the Aleut and Dena’ina as a treatment for sore throat, making tea to gargle from the leaves.


The woolly geranium is a tall perennial herb that grows from a horizontal rootstock or rhizome 5-10 mm in diameter. The stem is erect and 10-90 cm (4-36 in) tall. Leaves are large, alternate, slightly hairy, and deeply divided and toothed, somewhat resembling a maple leaf. The flowers are blue to violet or lavender with 5 petals about 2.5 cm (1 in) in diameter. The petals have dark, radial stripes and a deep purple stamen. Flowers may be singular or in a cluster of 2-3 (possibly up to 5). It also has smaller, bristly sepals. The seed capsules are thin, pointed, hairy carpels that look somewhat like the bill of a crane (hence a common name “cranesbill”) that split open suddenly, expelling the seeds.
