Creamy pea vine is endangered or threatened in several states in the US. It is a slender, climbing perennial from up to 3ft tall. Has 5-10 pea-like creamy-white flowers in clusters in early summer. Often found in open woods.
Although not poisonous care should be exercised as some plants from this genus cause a type of poisoning called lathyrism, which results from livestock eating too much vetchling seed over long periods of time.
