Synonym(s):

USDA Symbol: CLLI2

USDA Native Status: L48 (N), CAN (N)

A strong, woody or semi-woody climber to 20 ft. or more. The wide clusters of creamy-white blossoms, from leaf axils on the upper portions of the plant, occur in such profusion they impart a white color to the whole mass of growth. These are followed by light-catching, silky seed plumes. Deciduous leaves are pinnately compound with 5-7 leaflets.

This species’ traditional name, Pepper Vine, referred to the acrid, peppery taste of the stems and leaves, which Native Americans chewed as a remedy for colds and sore throats. It is said that the crushed roots were placed in the nostrils of tired horses to revive them. Caution is advised: The genus is known to have poisonous species.
