A deciduous,  herbaceous (non-woody) soft-stemmed perennial with fern-like leaves. The stems are 12-18 inches tall and bear several large, extensively divided leaves. The solitary flowers are about 1 inch long. Its four purple sepals are joined for much of their length to form a striking furry “vase” that gives the flower one of its common names.  Each flower has several wooly ovaries, which develop long, feathery styles as they mature into hard, single seeded fruits. Dense hair covers the entire plant. It is in flower from May to June, and the seeds ripen from July to September.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. Found in moist open areas of plains, hills and woods, up to 2,500 meters.

Medical Uses
A decoction of the leaves has been used to treat headaches. The root has been used in the treatment of congested nose pain.
