Grow Actinidia arguta 'Issai' when you want an edible, vigorous vine that also looks great on a pergola, arbor, fence, or strong trellis. In late spring, it produces small, fragrant, greenish-white flowers, followed by smooth-skinned, grape-size kiwiberries that ripen from late summer into fall. This selection is noted for having perfect flowers, so it can set fruit without a separate pollinator vine, which makes it a good fit for smaller gardens and patio plantings.
Give your hardy kiwi a sturdy support and room to climb; mature vines can be large and the woody stems get heavy over time. Plant in rich, moist, well-drained soil and keep it evenly watered, especially while establishing and during fruit development. Place it in full sun for best growth and fruit quality, though it will also grow in partial shade. It is hardy in USDA Zones 3-7, but young plants benefit from protection from drying winds and late frosts.
Prune regularly to keep the vine manageable and to encourage productive new growth. Do major pruning while the plant is dormant (winter), then do light training and touch-up pruning during the growing season as needed. With consistent training, you can direct the vine to cover a structure neatly and keep harvest within reach.
