description Clematis Overview

Clematis is a large genus comprising roughly 300 species of mostly woody, climbing vines within the buttercup family, Ranunculaceae. Native primarily to temperate regions of the Northern Hemisphere, these plants are distinguished by their showy, prominent flowers which vary widely in shape, size, and color across species and cultivars. They are widely utilized in horticulture as ornamental climbers for trellises, arbors, and pergolas. Intensive hybridization efforts, particularly in 19th-century Britain and France, have produced numerous large-flowered garden hybrids.

help Clematis FAQ

Is clematis a shrub or a climbing vine?

Most clematis are woody climbing vines in the buttercup family, Ranunculaceae. The genus contains roughly 300 species, many of which climb by wrapping their leaf stalks around supports.

How much sun does clematis need?

Many clematis varieties flower best with several hours of sun, while their roots benefit from cooler, protected soil. Exact light needs vary across the large genus, so the species or cultivar matters.

Why do clematis flowers come in so many different forms?

Clematis includes about 300 species from mainly temperate parts of the Northern Hemisphere. Their flowers vary widely in size, color and shape, which is why garden cultivars can look very different from one another.

Can clematis climb a wall without a trellis?

Clematis usually needs a support with thin surfaces that its leaf stalks can wrap around. A trellis, wire grid or other narrow support is more suitable than a completely smooth wall.
