ISSAI HARDY KIWI You’ll enjoy fruit and pretty variegated leaves on this hardy kiwi, which produces small seedless fruit. For more and larger kiwis, plant a male vine, as well. Give this climber a strong support in the warmer end of its hardiness range, because vines can reach 15 to 25 feet. Full sun to part shade is best. Vines are hardy in zones 4 to 8.
