Height 20-80 cm. A deciduous perennial with solitary flowering stems. The basal, hairy leaves with long stalks are the most distinctive feature. The leaf blade is divided into 5 (rarely up to 9) toothed leaflets, with all but the lowermost pair joined together. Flowers are tiny funnel-shaped in compact clusters 5-7 mm long. Flower colour ranges from greenish-white to blue or purple. The stamens (male sexual structures) are very noticeable and extend past the petals. After flowering, tiny round capsules develop, each containing one to three seeds.
