Plant Details

The most familiar clematis species are deciduous vines that clamber into trees and over fences and arbors; exceptions include the evergreen Clematis armandii and a few interesting freestanding or sprawling perennials. Flowers are attractive in all kinds, spec- tacular in many. The clustered true flowers are tiny and incon- spicuous; the showy part consists of petal-like sepals that surround them. Blossoms of most are followed by fluffy clusters of seeds with tails, often quite effective in flower arrangements. Leaves of vining kinds are dark green, usually divided into leaflets; leafstalks twist and curl to hold plant to its support.

armand clematis, evergreen clematis

clematis armandii

  • Zones MS, LS, CS; USDA 7-9.

Makes privacy screen if not allowed to become bare at base. Slow to start but races when established.
