These plants include woody, deciduous vines as well as herbaceous and evergreen varieties. They also vary greatly among species, with different flowering forms, colors, and blooming seasons, though most bloom sometime between early spring and fall. Growing clematis successfully depends on the type chosen; however, most plants share the same basic growing requirements.
For proper care of clematis, clematis vines prefer sunny locations (at least six hours of sun needed for blooming) but the soil should be kept cool. An easy way to accomplish this is by planting some type of ground cover or shallow-rooted perennial plants around the clematis. A 2-inch layer of mulch can also be incorporated to keep the roots cool and moist. Growing clematis vines must be supported in some fashion as well. The type of support system is usually dependent on the variety grown. For instance, poles are acceptable choices for smaller growing clematis vines, which can range anywhere from 2 to 5 feet in height. Arbors may be more suitable for growing larger types, which can get 8 to 12 feet. Most varieties, however, do quite well growing along a trellis or fence.
