Potted Issai Hardy Kiwi (Self-Pollinating)
Potted Issai Hardy Kiwi (Self-Pollinating)
Available only for pick-up at nursery.
Species: Actinidia arguta
History: Issai* hardy kiwi originated in Japan and is popular since it is a self-pollinating variety.
Why We Grow It: An exceptionally sweet variety, with around 20% natural sugars. Hardy kiwis have smooth, edible skin (unlike their more common southern counterparts). No need to peel these emerald treats, enjoy as they are! This vine reaches 12-20' long, so be prepared to trellis up to 80lbs of fruit per year. While this variety is self-pollinating and delicious, one downside is it is prone to break buds early in spring, and the new shoots are tender; if your plant has begun growing and a heavy frost is expected, it's best to wrap in burlap/tarps/old sheets.

*Although without the Japanese characters it is uncertain what the English translation is supposed to be, it is possible the name 'issai' here comes from the Japanese word for 'everything/all/absolutely.'
