Clematis are of the Ranunculaceae botanical family. The majority of clematis are climbers. There are several hundred species of clematis, with the majority of these very hardy.

Clematis enable the gardener to have masses of bloom from early spring to late fall. To accomplish this, varieties with different bloom times can be grown together or planted in complimentary areas of the garden. Clematis can be chosen to enrich any garden, no matter how large or small. Some of species, if left to wander will easily grow 30' while others mature at 6-8'.

The hybrids are more compact with the majority maturing at the 8-12' range.

Most clematis varieties produce single flowers. These range in size from as small as 1" to 10". Some varieties produce double flowers, others produce both single and double flowers. Most double flowering varieties will bloom double on the previous season's growth, early in spring. They will then bloom single on the current season's growth in late summer or early fall. If pruned improperly, these varieties will produce single blooms only.

The blooms of the clematis often change color, some very markedly through the life of each flower, particularly when grown in the full sun. The pastel colors will hold their color best if grown in some shade. After the flowers are finished, the very attractive seed heads stay on the plant and make a welcome addition to flower arrangements. If left on the plant they sometimes remain well into winter.
