General Description

One of the most drought-tolerant flowering clematis vines extant, the scarlet clematis' blue-green leaves and red flowers highlight this plant's beauty. It is native only to the southeastern Edwards Plateau in central Texas. This deciduous woody vine blooms from very early summer to fall, often reblooming up until the killing frost.

The three leaflets comprising each leaf are rounded and a medium green with a hint of blue-green. Leaves are held in opposite pairs on the vining stems. In the warmth of summer, purplish stems arise from the base of leaves and bear a tulip-shaped scarlet to red flower. Each bud opens to reveal four, petal-like sepals with a creamy center in the base. As the flowers age, they are held outwards, better attracting insects for pollination and resulting in attractive spidery seed heads that look like fireworks.

Grow the scarlet clematis in partial sun to partial shade in fertile, well-drained soils that aren't dense and clay-based. Moreover, the soil should be alkaline to neutral in pH and kept cool and moist with mulch, particularly in regions with hot summers. Prune it back annually in late winter to shin height to renew the plant; it blooms on current season's growth. Use it as a trellised vine upon a garden wall or on a post where irrigation doesn't reach. Although highly sun and drought tolerant, an evenly moist soil in summer's heat promotes the healthiest, most robust plants. Good air circulation is needed in humid regions to prevent powdery mildew.

While garden centers may market some red-flowering cultivars as being scarlet clematis selections, they are most likely hybrids. The scarlet clematis was often interbred with larger-flowering clematis species to create new cultivars more vivid flower colors, often with curling sepals.
