Whether you want to grow a conversation piece or sweet and tangy fruits, our cold hardy kiwi plants are a great option. The plants grow similar to grape vines—and can reach a height of 8' in the first year. They make an excellent privacy screen when grown on a trellis. When shopping for kiwi vines for sale online, consider your hardiness zone and growing conditions. Hardy kiwis prefer full sun to partial shade. Finally, keep in mind that at least one male kiwi plant is needed for every five female kiwis for proper pollination.
