Add vertical interest to your garden with perennial vines. Several types of vines are available, including evergreen, fruiting and flowering vines. Because they provide edible treats, fruiting vines, such as kiwi vines, are a fun addition to the garden. Like other vines and climbers, these vines also provide beautiful foliage and vertical interest—and can also be grown as privacy screens. Direct Gardening offers a wide selection of vines for sale. When buying perennial vines, make sure they are suitable for your hardiness zone. Other factors to consider are their pollination requirements, mature height and spread, sunlight requirements (full sun, partial shade or full shade), soil requirements and pruning needs.
