About Antirrhinum majus 'Twinny Peach'
Antirrhinum majus 'Twinny Peach' · also called Twinny Peach Snapdragon, Double Peach Snapdragon · flowering
A dwarf, double-flowered snapdragon and All-America Selections winner, 'Twinny Peach' bears soft peach, apricot, and cream open-faced double blooms on compact, well-branched plants. Bred for heat tolerance and tidy bedding, it suits borders, containers, and the front of beds. It flowers prolifically in cool-to-mild weather and needs no staking.
Preferred mix: Fertile, well-drained, neutral to slightly alkaline soil or quality potting mix
Watch for — Rust: Orange pustules under the leaves spread in humidity. Space plants, keep foliage dry, remove infected leaves, and avoid replanting snapdragons in the same soil yearly.
Why antirrhinum majus 'twinny peach' needs this mix
Antirrhinum majus 'Twinny Peach' 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 'Twinny Peach' 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 'twinny peach' 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 'twinny peach' — 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 'twinny peach' 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 'twinny peach'?
Antirrhinum majus 'Twinny Peach' 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 'twinny peach', 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 'twinny peach' 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 'twinny peach' covers the timing and technique step by step.
