Climbing Hempweed is a branched, slender-stemmed perennial vine, native to South America.

Oppositely arranged leaves are heart-shaped or triangular with an pointed tip and a broad base, 4-13 cm long. Strongly fragrant flowers, each 3-5 mm long, are arranged in dense corymbs in leaf axils or at the end of branches. Each flower-head is 4.5-6 mm long. Individual florets are white to greenish-white, 4 in each head. Climbing Hempweed is found at altitudes of 700-1200 m.
