About Clematis 'Comtesse de Bouchaud'
Clematis 'Comtesse de Bouchaud' · also called Comtesse de Bouchaud clematis, mauve pink clematis · flowering
A reliable large-flowered climbing clematis bearing rounded, satiny mauve-pink blooms with cream anthers from midsummer into early autumn. A Group 3 cultivar, it flowers on new growth, so hard prune in late winter. Vigorous, free-flowering and disease-resistant, it suits trellises, obelisks and trained walls, and tolerates a north or east aspect.
Preferred mix: Fertile, humus-rich, moisture-retentive but well-drained loam
Watch for — Clematis wilt: Sudden collapse of stems, usually from a fungal infection (Calophoma). Cut affected stems back to healthy tissue or ground level; deep planting helps the plant regenerate from below soil.
Why clematis 'comtesse de bouchaud' needs this mix
Clematis 'Comtesse de Bouchaud' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Clematis 'Comtesse de Bouchaud' evolved on stony, sun-baked slopes — its roots expect to dry out hard and quickly between rains, so the mix must drain almost as fast as you pour.
- A lean, low-nutrient mix keeps growth firm and aromatic; a rich one gives soft, sappy, flavourless growth that flops and rots.
- It tolerates and often prefers a slightly alkaline soil, the opposite of most houseplants.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons clematis 'comtesse de bouchaud' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Rich, moisture-holding compost is the classic killer of clematis 'comtesse de bouchaud' — especially over a cold, wet winter, when the base of the plant simply rots.
- A peaty, acidic potting mix is doubly wrong: too wet and the wrong pH direction.
- No grit means the rootball stays damp for days, which a dry-climate root system never copes with.
Growing clematis 'comtesse de bouchaud' in ordinary rich, moisture-retentive compost. Lean it out with at least a third grit, and never let it sit wet over winter.
pH — does it matter for clematis 'comtesse de bouchaud'?
Clematis 'Comtesse de Bouchaud' likes neutral to slightly alkaline soil, roughly pH 6.5-7.5. If your soil or compost is acidic, a little garden lime or extra grit nudges it the right way — the one common plant where you may add lime.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged "herb" or "Mediterranean" mixes are usually fine for clematis 'comtesse de bouchaud', but most standard composts need cutting hard with grit. The DIY ratio above is cheap and exactly right.
Drainage and the pot
Sharp drainage is everything: a terracotta pot with a big hole, gritty mix and never a saucer left full. Raised beds suit these herbs outdoors for the same reason.
A gritty mix barely breaks down, so clematis 'comtesse de bouchaud' needs little repotting — refresh the top layer and the grit every couple of years rather than potting on aggressively. When the time comes, our repotting guide for clematis 'comtesse de bouchaud' covers the timing and technique step by step.
