About Rolling Houseleek
Jovibarba globifera · also called Rolling Houseleek, Hen and Chickens Houseleek · flowering
Jovibarba globifera is a fascinating succulent native to rocky alpine and subalpine habitats across central Europe, best known for producing small, globe-shaped offset rosettes ('globi') that detach from the mother plant at the slightest touch and roll away to colonise new ground — the origin of its common name. Rosettes are flattened-globose, light green often with a red apical blotch, growing to about 3 cm across. It requires full sun and free-draining gritty soil, and is completely cold-hardy. Jovibarba is not individually listed by the ASPCA; treat as mildly-toxic until a direct species-level ASPCA confirmation is available.
Preferred mix: Sandy, gritty, extremely free-draining
Watch for — Crown rot after winter wet: Despite excellent cold hardiness, persistently waterlogged soil in winter causes root and crown rot. Always grow in sharply drained compost; raise containers on pot feet and add a top-dressing of grit to divert water away from the rosette collar.
Why rolling houseleek needs this mix
Rolling Houseleek is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Rolling Houseleek 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 rolling houseleek 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 rolling houseleek — 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 rolling houseleek 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 rolling houseleek?
Rolling Houseleek 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 rolling houseleek, 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 rolling houseleek 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 rolling houseleek covers the timing and technique step by step.
