Outstanding Qualities

Unlike the fuzzy-skinned kiwi fruit found at the supermarket the fruit of this species, Actinidia arguta, is about the size of a grape with smooth edible skin, although with a similar taste, yet sweeter. Another difference is the hardiness is much great, down to USDA Zone 4. The cultivar 'Issai' is particularly useful because a cross-pollinator is not needed, but will bear fruit on its own. In addition, this selection has a more restrained growth habit growing to from 12 to 20 feet.
