Growth

It has an inflorescence on stems 5-6 centimeters long, separate from the leaves, arising from a subterranean stem and deep carrot-shaped root that is 3–7 cm long. The long petioled leaves are palmately divided into 5 linear-elliptic leaflets that are 3-5 centimeters long. The flowers, borne in condensed spikes separate from the leaves, are purple and pea-like, and have a surprisingly strong scent, reminiscent of lemon furniture polish. The species has edible tuberous roots, high in protein.
