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.

In North America, Geranium erianthum is found in Alaska, the Yukon, British Columbia, and Alberta. It is also found in Asia in Japan, China, and eastern Siberia.

Wooly geraniums in Bristol Bay are blue. Surprisingly, they are sold here as garden ornamentals.

I’ve seen blue ones in the Anchorage area too. I’ve yet to see any white ones, but I hear they are out there! Also, thanks for the donation!
