About Geranium cinereum 'Ballerina'
Geranium cinereum 'Ballerina' · also called Ballerina cranesbill, Ballerina grey-leaved geranium · flowering
Geranium cinereum 'Ballerina' is a long-blooming alpine cranesbill forming a low rosette of soft grey-green leaves. From late spring it produces a long succession of cupped, pale lilac-pink flowers boldly veined and blotched in deep purple-maroon. Compact and sun-loving, it is ideal for rock gardens, troughs, gravel and the very front of well-drained borders.
Preferred mix: Gritty, sharply drained neutral to alkaline soil
Watch for — Crown and root rot: The single biggest killer, caused by heavy or wet soil, especially over winter. Plant in sharp drainage, add grit around the crown, and avoid mulching directly over the rosette.
Why geranium cinereum 'ballerina' needs this mix
Geranium cinereum 'Ballerina' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Geranium cinereum 'Ballerina' 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 geranium cinereum 'ballerina' 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 geranium cinereum 'ballerina' — 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 geranium cinereum 'ballerina' 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 geranium cinereum 'ballerina'?
Geranium cinereum 'Ballerina' 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 geranium cinereum 'ballerina', 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 geranium cinereum 'ballerina' 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 geranium cinereum 'ballerina' covers the timing and technique step by step.
