About Musk Stork's Bill
Erodium moschatum · also called Musk Stork's Bill, Musky Stork's Bill · herb
Erodium moschatum is an annual or biennial herb native to southern Europe, the Mediterranean basin, and western Asia, now naturalised on most continents including North America and Australia. It produces a spreading rosette of pinnately divided, musky-scented leaves and small pinkish-purple flowers from spring through summer. The young leaves are edible raw or lightly cooked and have been used as a wild vegetable and potherb for centuries. The key care fact is providing a sunny, well-drained position in neutral to alkaline soil. Not documented as toxic; mildly-toxic is the cautious classification as no specific ASPCA non-toxic entry exists for this species.
Preferred mix: Well-drained, sandy or loamy, neutral to alkaline
Why musk stork's bill needs this mix
Musk Stork's Bill is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Musk Stork's Bill 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 musk stork's bill 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 musk stork's bill — 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 musk stork's bill 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 musk stork's bill?
Musk Stork's Bill 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 musk stork's bill, 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 musk stork's bill 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 musk stork's bill covers the timing and technique step by step.
