Clusters of white flowers bloom in the spring. A coin-like pod contains a single seed. The vine can grow up to 60 or 70 feet long. The crushed roots, leaves, and bark release a compound containing rotenone. When put into water, it blocks oxygen uptake of gills in fish, immobilizing them. Native Americans used to gather stunned fish after throwing the crushed plants in the water. This is no longer legal to do. The bark separates into long, strong fibrous strips which can be used as rope for lashing timber in primitive construction. The wood has a pleasant rose-like smell and has been used in incense.
