Description: "Coarse, twining or creeping vine with thickened or tuberous roots. Stems up to 10 m long, somewhat woody, covered with long, yellow-brown hairs. Leaves alternate, trifoliate, with a rachis 8-20 cm long. Leaf margins wavy, leaf surfaces softly pubescent. Flowers in many-flowered axillary racemes 15-40 cm long. Calyx long-hairy, divided more than half way into five unequal lobes; corolla papilionaceous, violet with a yellow spot, and 14-20 mm long. Stamens ten, diadelphous. Fruit a densely brown-hairy, flat, oblong-linear pod 9-12 cm long, 8-12 seeded" (Whistler, 1983; p. 53).
Description from Flora of China online.
Habitat/ecology: "Riparian habitats, forest edges, woodland. A native of forest margins, occurring up to 2,000 m elevation. This nitrogen-fixing and fast growing vine can quickly cover shrubs and trees with a dense tangle of stems, smothering them and shading out all other vegetation. Stems easily root at nodes and form mats that may be more than 2 m tick. The vine is able to smother trees up to 35 m tall, eventually killing them" (Weber, 2003; p. 351). Wild forms grow between 30 and 1860 m. Cultivated forms are more common in high altitude areas up to 2700 m altitude (GPPIS).
In Hawaii, "naturalized in low elevation disturbed areas, at least up to 700 m" (Wagner et al., 1999; pp. 693-695). In Tonga, "frequent in thickets" (Yuncker, 1959; pp. 147-148).
Propagation: Primarily by runners and rhizomes. Limited spread by seed. "Seeds are dispersed by birds and mammals" (Weber, 2003; p. 351).
Native range: Eastern and southern Asia, into the Pacific as far as Tonga (GRIN).

Control:
Physical: Once established, the vine is difficult to control. Frequent close cutting will exhaust the plant's stored food supply in the roots and will eventually kill it. Control includes grazing by goats and persistent weeding or mowing. If manually controlled, all roots should be removed to prevent regrowth (Weber, 2003; p. 351).
Chemical: "An effective herbicide is triclopyr" (Weber, 2003; p. 351).
Biological: Biological control information from the publication "Biological control of invasive plants in the eastern United States".
