From Asia. Rampant woody vine climbs 20–30 ft. by stem tendrils. Large, handsome, three-lobed, 2 1/2–5-in.-wide leaves. In warm climates, leaves turn red and most drop in fall; more leaves come out, redden, and drop all winter. Many clusters of small, grapelike berries turn from greenish ivory to brilliant metallic blue in late summer and fall; attracts birds. Needs strong support: superb on concrete and rock walls or on sturdy arbors. Thin out and shorten stems each winter; dig out suckers. You can cut the vine to the ground and still get berries, since it blooms and fruits on new growth.
