Foliage
The fetid smelling leaves are alternate, simple, toothed, up to 8 in. (20 cm) long and 6 in. (15 cm) wide. In the early season (annual), or first year of growth (biennial) the plant is represented by a rosette.
Flowers
Flowering occurs in spring to early fall. Flowers are cream to green, five-lobed, 2 in. (5 cm) wide and have purple throats.
