Culture
Grow in average, medium moisture, well-drained soil in full sun to part shade. Planting in infertile soil may temper somewhat rapid growth habit. Needs frequent pruning, including an annual winter pruning of each stem back to 8-10 buds and an annual summer pruning of excessively long shoots.
Noteworthy Characteristics
Actinidia arguta, commonly known as hardy kiwi or tara vine, is a deciduous, fast-growing, twining woody vine that is typically grown for its attractive foliage and edible fruit. It is native to woodlands, mountain forests, streamsides and moist locations in eastern Asia, China and Japan. It grows to 25-30' or more, but growth is often so rampant that this vine, in its native habitat, may climb to as much as 100' into large trees. Broad-ovate to elliptic deep green leaves (3-5" long) emerge in spring, scented greenish-white flowers (to 3/4" long) bloom in June and edible grape-sized smooth-skinned fruits (to 1 1/4" long) mature in September-October. Species plants are dioecious (separate male and female plants), with at least one male pollinator needed for fruit set on female vines. It tastes similar to, though slightly sweeter than, its larger-fruited relative, the true kiwi, Actinidia deliciosa, which can not be grown north of Zone 8.
Genus name comes from the Greek word aktis meaning ray in reference to how the plant growth radiates like the spokes of a wheel.
Specific epithet means sharply toothed or notched in reference to the toothed leaves.
Problems
No serious disease or insect problems.
Uses
This fast growing vine can be grown both for its beautiful foliage and its fruit. Rapid growth habit makes it suitable for a variety of cover-type uses such as on a trellis, arbor, patio overhead, fence, or wall.
