About Antirrhinum majus 'Sonnet Pink'
Antirrhinum majus 'Sonnet Pink' · also called Sonnet Pink Snapdragon, Mid-height Pink Snapdragon · flowering
A mid-height snapdragon from the well-branched Sonnet series, valued for sturdy stems and uniform soft-pink spikes that bridge bedding and cutting use. 'Sonnet Pink' flowers earlier and more freely than taller types, staying upright without much staking. It performs best in cool seasons, rewarding deadheading with a strong second flush of dragon-mouth blooms.
Preferred mix: Fertile, well-drained, neutral to slightly alkaline soil
Watch for — Stem and crown rot: Soft, collapsing stems in soggy soil. Plant in sharply drained ground, avoid overwatering, and never let mulch pile against the crown.
Why antirrhinum majus 'sonnet pink' needs this mix
Antirrhinum majus 'Sonnet Pink' is a Mediterranean dry-hillside plant — it wants a lean, sharply drained, slightly alkaline mix, and rots fast in rich, water-holding soil.
- Antirrhinum majus 'Sonnet 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 antirrhinum majus 'sonnet 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 antirrhinum majus 'sonnet 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 antirrhinum majus 'sonnet 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 antirrhinum majus 'sonnet pink'?
Antirrhinum majus 'Sonnet 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 antirrhinum majus 'sonnet 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 antirrhinum majus 'sonnet 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 antirrhinum majus 'sonnet pink' covers the timing and technique step by step.
