Size and Method of Climbing
Hardy kiwi is a vine that grows vigorously and may grow up to 25 or 30 feet long.
It is a twining vine. Twining vines climb by twisting their stems or leaf stalks around a support. This type of vine grows well on trellises, arbors, wires or chain-link fences.
Full sun to partial shade. Best in rich, well-drained soils, but tolerates a range of soil types.
Prune heavily in winter. Fruit will be produced on new growth.
Disease, pests, and problems
No serious problems.
Native geographic location and habitat
Native to Asia.
Leaves are arranged alternately. The simple green leaves are oval is shape and somewhat rounded at the base. The margin of the leaf is toothed. Leaf stalks are often reddish.
Very little fall color (sometimes a mild yellow).
Male and female flowers are on separate plants (dioecious). Flowers are small and fragrant, green-white and not very showy. Flowering occurs in late spring to very early summer.
The fruit is an edible berry (kiwi), smaller than the kiwi that are found in grocery stores (about 1 inch long). A male plant is needed for the female plant to set fruit.
