Fern-leaved Clematis

Clematis cirrhosa

The Story

Plant Bio

Clematis cirrhosa, winter clematis, is an evergreen climber from the Mediterranean, reaching four to twenty feet depending on shelter and support. Dark green leathery divided leaves cover wiry stems, and nodding bell-shaped cream flowers, often freckled inside with maroon, open through winter and early spring, followed by silky seedheads.

It flowers in the depths of winter and then goes summer-dormant, dropping much of its foliage and looking half dead in July — that is its Mediterranean cycle, not a problem, and it recovers in autumn. Give it a warm sheltered wall, since the winter flowers are spoiled by hard frost and cold wind. The nodding bells are best seen from below.

Uses & Benefits:

Ornamental UsesFreckled cream bells through winter on an evergreen frame, then silky seedheads.
Practical UsesFlowers when nothing else on a wall does, and needs very little water once established.
Ecological BenefitsBees take nectar and pollen from the winter flowers on mild days.

Planting

How to Grow

  1. Plant against a warm, sheltered wall or fence.
  2. Give it full sun to partial shade and free drainage.
  3. Site it where the nodding flowers can be seen from below.
  4. Expect summer leaf drop; do not treat it as failure.
  5. Prune lightly straight after flowering only.
  6. Wear gloves; the sap blisters skin.

Pro Tip

It goes bare and shabby in midsummer by design — that is Mediterranean dormancy, and it refoliates in autumn without help.

Common Questions

Fern-leaved Clematis questions

What zones can Fern-leaved Clematis grow in?

Is Fern-leaved Clematis deer resistant?

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

When does Fern-leaved Clematis bloom?

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

Does Fern-leaved Clematis need full sun?

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

Is Fern-leaved Clematis drought tolerant?
