About Mediterranean Everlasting
Helichrysum stoechas · also called Mediterranean Everlasting, Common Shrubby Everlasting · flowering
Helichrysum stoechas is a compact, aromatic, evergreen subshrub native to the Mediterranean basin, including south-west Europe and northern Morocco. It thrives in full sun and sharply drained, poor-to-moderately fertile neutral to alkaline soil, where it produces clusters of small, papery golden-yellow flowerheads through summer. The single most important care fact is that it will not tolerate waterlogged soil or prolonged winter wet, which causes root rot and crown collapse far more readily than cold does. Helichrysum is not listed by the ASPCA as toxic to cats or dogs; treat as mildly-toxic due to limited formal evaluation.
Preferred mix: Poor to moderately fertile, sharply drained, neutral to alkaline
Watch for — Root rot: The most common cause of plant death. Caused by overwatering or poorly drained soil; stems blacken at the base and the plant wilts despite moist soil. Improve drainage and reduce watering immediately.
Why mediterranean everlasting needs this mix
Mediterranean Everlasting is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Mediterranean Everlasting 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 mediterranean everlasting 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 mediterranean everlasting — 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 mediterranean everlasting 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 mediterranean everlasting?
Mediterranean Everlasting 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 mediterranean everlasting, 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 mediterranean everlasting 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 mediterranean everlasting covers the timing and technique step by step.
