The ‘Issai’ Kiwi (Actinidia arguta ‘Issai’) is a hardy and self-fertile fruit vine, producing small, smooth kiwis (without fuzzy skin) that can be eaten whole. The fruits are sweet green, juicy, and aromatic.
Unlike several hardy kiwis, ‘Issai’ is self-fertile, meaning a single plant can produce fruit. However, the presence of another hardy kiwi can improve yield.
In spring, the plant produces small, fragrant white flowers, followed by a harvest usually in September in Quebec.
It is a vigorous, climbing vine that requires a trellis or sturdy structure.
The flowers are visited by pollinators, including bees.
