Clematis

Clematis armandii

The Story

Plant Bio

Clematis armandii, Armand clematis, is a vigorous broadleaf evergreen climber from central and southern China, reaching fifteen to thirty feet. Long leathery three-parted leaves hang in dark glossy curtains from twining stems, and masses of small white star-shaped flowers open in early spring with a strong vanilla-almond scent.

It is one of very few evergreen clematis, so it screens all year rather than only in summer — but it is heavy, and a mature plant will pull down a flimsy trellis. Give it a solid support from the start. It flowers on the previous year's wood, so prune within a few weeks of flowering, and cut only lightly: it resents hard pruning and can be slow to recover.

Uses & Benefits:

Ornamental UsesDark evergreen curtains of leathery foliage with masses of scented white flowers in early spring.
Practical UsesScreens year round, which no deciduous clematis does, and grows fast once established.
Ecological BenefitsBees, butterflies and hummingbirds all work the early flowers.

Planting

How to Grow

  1. Provide a genuinely solid support; it gets heavy.
  2. Plant in full sun to partial shade in drained soil.
  3. Shelter it from cold drying winds, which brown the leaves.
  4. Prune within weeks of flowering, and only lightly.
  5. Mulch the root area to keep it cool.
  6. Wear gloves when pruning; the sap blisters skin.

Pro Tip

A mature plant is genuinely heavy — build the support for a small tree, not for a clematis, before you plant it.

Common Questions

Clematis questions

What zones can Clematis grow in?

Clematis is hardy in USDA Zones 7–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Clematis deer resistant?

Yes — Clematis is rated deer-resistant. Deer typically pass it over, though extreme hunger can override any plant's defenses.

When does Clematis bloom?

Clematis typically blooms in early spring through mid-spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Clematis need full sun?

Clematis does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
