There are two varieties for the plant. Variety bracteata has stems with sparse to moderate appressed hairs. Variety comosa has stems with dense spreading to retrorse hairs. As seen above, the flowers can be blue-purple or white.
The roots of this species form nodules which can be eaten, hence the common name of the plant.
