Take your garden to new heights—and produce sweet and tangy fruits—with our cold hardy kiwi plants. These plants grow similar to grape vines, and often can reach up to 8 feet tall in the first year. When grown on a trellis, they make an excellent privacy screen. They're also sure to be conversation starters when visitors see the fruits. When buying kiwi plants for sale, make sure they are suitable for your hardiness zone. Hardy kiwi vines can be grown in full sun to partial shade. For proper pollination, one male kiwi plant is needed for every five female kiwi vines.
