The leaves have a 2 to 8 millimeter long petiole. The leaf blade is simple, paper-like to leathery, 2 to 7 rarely to 13 inches long and 1 to 3 rarely to 5.5 inches wide, elliptical to elongated elliptical, pointed or blunt with a wedge-shaped to rounded base. The upper side of the leaf is dull green, the underside is lighter and hairy on the central nerve. Four to six, rarely seven pairs of nerves are formed that protrude from the underside.
The flowers are 100 to 500 in hairy, 4 to 11 centimeters long and 3 to 8 centimeters wide panicles . The single flowers grow on 1 to 5 millimeter long stems. They have an approximately 1 to 1.5 millimeter wide, bald or hairy calyx , a 3.5 to 5.5 millimeter wide corolla and a corolla tube that is slightly shorter than the corolla lobes. The stamens reach up to the corolla lobes or slightly beyond, the anthers are about 1 millimeter long.
The fruits are round, 5 to 8 millimeters in diameter, black and slightly frosted berries .
The number of chromosomes is 2n = 46.

The natural range is in the temperate to tropical zone of Asia in the Chinese provinces of Anhui , Fujian , Guangdong , Guangxi , Guizhou , Hubei , Hunan , Jiangsu , Jiangxi , Sichuan , Yunnan , Zhejiang and Hong Kong , on Taiwan, in Laos and Vietnam. It was naturalized in the south of Africa, Australia, New Zealand and the USA. The species grows in steppes and dry forests at heights of 200 to 2700 meters on moderately dry to fresh, weakly acidic to alkaline, sandy-loamy to loamy, nutrient-rich soils in sunny to light-shady locations. It loves warmth and is usually frost hardy.
