It is a woody vine with nodes every few centimeters which produce leaves and flowers. The leaves are made up of several dark green lobed leaflets, each one to three centimeters wide. From each leaf-bearing node grows an inflorescence of one to three flowers with narrow petallike sepals in shades of light yellow.

It is quite variable in appearance, especially across varieties. In general the hairy stem reaches up to about half a meter tall and has many large hairy leaves divided into lance-shaped lobes. The inflorescence appears at the tip of the stem and bears a solitary flower. The flower is made up of an urn-shaped cup of deep purple-blue petal like sepals, which are fuzzy and have pointed or rounded tips. Rare individuals have white or pinkish sepals. There are no true petals. The fruit is a hairy achene with a very long beak and a plume on the end; it is dispersed by wind.
