Actinidia valvata

About

Actinidia valvata is a species of flowering plant in the Chinese gooseberry family Actinidiaceae, native to southern China. A deciduous climbing shrub, it is found in open woodlands and in thickets, preferring mountain valley bottoms, around 1,000 m (3,300 ft) above sea level. As a crop wild relative of kiwifruit, it is being studied for its resistance to waterlogging, with an eye towards using it as a rootstock.
