There are more than 300 species and hundreds of hybrids of clematis. Most clematis are woody, deciduous vines while others are shrub, or trailing types. Some species bloom in spring; others, in mid-to late summer. Most clematis are hardy in USDA Hardiness Zones 4 to 8 and native to North America. The blooms are spectacular with some flowers reaching up to 10 inches across! These showy flowers in the form of saucers, bells, tubes, tulips, open bells, doubles, and semi-double. The flowers are usually in the cool shades of purple or pink though they do come in a stunning array of tones including blue, white, magenta, yellow, and bicolor. Clematises appreciate a trellis, post, or stationary structure to climb; without something, the vine will sprawl, including over the ground. Hummingbirds, bees, and butterflies love their blooms. Grow in fertile, medium moisture, well-drained soils in full sun to part shade. Vining hybrids are best sited in locations where the flowering parts of the vine are in sun to part shade but the roots are shaded. Some light afternoon shade is usually beneficial in hot and humid summer climates. Roots should be kept cool, shaded and uniformly moist. Root areas may be shaded with perennials, annuals or small shrubs. A thick root mulch is appreciated. Do not allow soils to dry out.
