Description

Armand clematis is a woody, perennial vine that climbs by twining petioles. It is a member of the buttercup family (Ranunculaceae). Its native region is central and south China to Burma. The species epithet honors Catholic missionary and naturalist Armand David (1826–1900), who explored China and sent back hundreds of natural history specimens to Europe.

Armand clematis prefers full sun to partial shade and moist, organically rich soil with good drainage and a neutral pH. It is intolerant of wet soils. A layer of mulch will help to keep the roots cool and moist. Feed it with a low nitrogen, slow release fertilizer every 4 to 6 weeks throughout the growing season. The plants are propagated by division or stem cutting. 

It should be grown with support, against a lattice or trellis. The vine can be quite aggressive in its growth, reaching 15 to 30 feet high and 10 to 15 feet wide but is relatively easy to keep in bounds with periodic pruning. Armand clematis blooms on old wood, so prune it after flowering (Type 1). This plant attracts bees, butterflies, and hummingbirds, which makes it a great addition to butterfly and pollinator gardens. 

It is recommended for Asian, winter, and cottage gardens. Let it climb a rock wall or other vertical space, even trees in a woodland garden. With good support, it serves as an attractive, living privacy screen.

Quick ID Hints:
