Clematis

Clematis x tangutica

The Story

Plant Bio

Clematis x tangutica, golden clematis, is a vigorous deciduous climber of central Asian parentage, reaching twelve to fifteen feet. Finely divided blue-green pinnate leaves cover twining stems, and nodding lantern-shaped yellow flowers with unusually thick waxy petals open from summer into autumn, followed by large silky seedheads.

The seedheads are as good as the flowers and last far longer — silvery plumed spheres that catch light through autumn and often into winter, so resist deadheading. It flowers on the current season's wood, which makes pruning simple: cut the whole thing to about a foot in late winter and it rebuilds and flowers the same year.

Uses & Benefits:

Ornamental UsesNodding waxy yellow lanterns through late summer, then silvery plumed seedheads into winter.
Practical UsesSimple to prune, drought tolerant, and untroubled by the wilt that plagues large-flowered clematis.
Ecological BenefitsButterflies, hummingbirds and pollinators work the flowers over a long season.

How to Grow

  1. Give it a support at least twelve feet tall.
  2. Plant in full sun to partial shade with cool roots.
  3. Mulch or shade the root area, not the top growth.
  4. Cut the whole plant to about a foot in late winter.
  5. Leave seedheads for autumn and winter interest.
  6. Wear gloves when pruning; the sap blisters skin.

Pro Tip

This is a group-three clematis, so simply cut everything to a foot in late winter — no judgement about old versus new wood needed.

Common Questions

Clematis questions

What zones can Clematis grow in?

Clematis is hardy in USDA Zones 4–9. 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 late spring to early fall through early fall. 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.

Is Clematis drought tolerant?

Yes — once established (usually after the first full season), Clematis handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
