About Felty Germander
Teucrium polium · also called Felty Germander, Silver Germander · herb
Teucrium polium is a compact, silvery-grey subshrub native to dry, rocky, often calcareous habitats throughout the Mediterranean basin and into the Middle East, where it has a long history of medicinal use. Its intensely woolly, tomentose stems and leaves give it a distinctive silvery-white appearance; small white to lavender flowers appear in dense terminal clusters from mid-summer into autumn. Full sun and impeccably drained, alkaline soil are mandatory — it is among the most drought-tolerant germanders. The plant is mildly toxic; hepatotoxic diterpenes documented in the genus make ingestion by pets or people inadvisable.
Preferred mix: Sharply drained, sandy or gritty, alkaline to neutral; poor fertility is beneficial
Watch for — Root and crown rot: Winter wet is the primary cause of plant death; this species absolutely requires perfect drainage and often benefits from being grown in a raised scree bed or alpine house in wetter UK climates.
Why felty germander needs this mix
Felty Germander is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Felty Germander 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 felty germander 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 felty germander — 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 felty germander 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 felty germander?
Felty Germander 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 felty germander, 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 felty germander 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 felty germander covers the timing and technique step by step.
