Parthenocissus semicordata (= P. himalayana)
A robust, deciduous climber, distributed from the Himalayas to Thailand and Malaysia, where it grows in shrublands and forests at elevations between 500 and 3800 m. It has smooth, tripartite, dark green leaves and inconspicuous, yellowish-green flowers, followed by black, edible, sweet fruits (grapes) that can be used for jellies or sauces. Parthenocissus semicordata will adapt well in most humid, warm-temperate climates in USDA Zones 9 and above. The seeds need cold stratification for 6 weeks after sowing, but even then, germination may be somewhat erratic.
