About Neglected Pink
Dianthus pavonius · also called Neglected Pink, Peacock-eye Pink · flowering
Native to sunny grasslands and rocky slopes in the southwestern Alps and Pyrenees up to 2,900 m elevation, Dianthus pavonius (syn. D. neglectus) is a compact, cushion-forming alpine pink that demands full sun and sharply drained, gritty, neutral to slightly alkaline soil. Its fragrant single flowers are deep rose-pink with a distinctive buff-coloured reverse to the petals, appearing in summer, making it a jewel for rock gardens and scree. The single most critical care point is ensuring perfect drainage year-round, as even brief waterlogging at the crown will kill the plant. According to the ASPCA, Dianthus (Pinks) are toxic to cats and dogs.
Preferred mix: Sharply drained gritty loam or sandy soil, neutral to slightly alkaline
Watch for — Crown rot (Fusarium / fungal): Waterlogged soil or organic mulch touching the crown leads to rapid stem-base rot, which is usually fatal. Ensure perfect drainage, use a grit collar, and position the plant so the collar sits slightly proud of soil level.
Why neglected pink needs this mix
Neglected Pink is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Neglected Pink 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 neglected pink 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 neglected pink — 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 neglected pink 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 neglected pink?
Neglected Pink 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 neglected pink, 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 neglected pink 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 neglected pink covers the timing and technique step by step.

What is the best soil mix for neglected pink?
2 parts standard peat-free compost or loam : 1 part coarse horticultural grit : 1 part perlite or coarse sand. Neglected Pink 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.
Can I use normal potting soil for neglected pink?
Rich, moisture-holding compost is the classic killer of neglected pink — especially over a cold, wet winter, when the base of the plant simply rots.

Does neglected pink need a special pH?
Neglected Pink 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.
Should I buy a bagged mix or make my own for neglected pink?
