What to Eat
The tender young leaves are eaten as greens in spring, both fresh and cooked, though they are generally small, sparse, and of modest food value — flavour is pea-pod-like but more bitter than commercial pea pods. The seedpods of this species are not reported edible. Flowers appear from April to September, with young pods following shortly after the blossoms. Yields can be unreliable as plants are prone to being eaten by animals or lost to disease before pods mature. The plant was reportedly eaten by the Karok Indians of the northwest, though plant distributions suggest possible species confusion in that record. All species in the genus contain toxic compounds called lathyrogens, which can cause neurolathyrism and osteolathyrism if consumed in large quantities or over long periods. Boiling reduces but does not completely eliminate these toxins.
