Description

Clematis armandi is a deciduous or evergreen vine that climbs by twisting stems and petioles. It has shiny, dark green leaves with clusters of star-shaped white flowers that bloom in late winter with a vanilla-like fragrance. It blooms on old wood, so it should not be pruned until after flowering. The vine can be quite aggressive in its growth but is relatively easy to keep in bounds with periodic pruning. It should be grown with support, against a lattice or trellis.  

This vine prefers full sun and cool roots in humusy moist soils. It is intolerant of wet soils. Mulch around the plant to help keep the roots cool and moist and give it winter protection in zone 7.

Quick ID Hints:

  • Leaflets are long, leathery and droopy
  • Large white flowers are fragrant, in clusters
  • Woody evergreen vine with opposite, ternately compound leaves
  • Persistent achenes are plumed, in clusters
