Antirrhinum majus 'Chantilly Peach' · also called Chantilly Peach snapdragon, Butterfly snapdragon · flowering

Chantilly Peach is an elegant tall snapdragon bearing open-faced, flaring blooms in soft peach flushed with apricot and rose, unlike the classic closed 'dragon mouth' flower. Growing 60–90 cm, it is superb for cutting gardens and cottage borders, attracting bees and butterflies. It thrives in cool weather and full sun with fertile, well-drained soil.

Mature size: 60–90 cm tall, 25–30 cm wide

Watch for — Powdery mildew: White powdery coating on leaves in warm, dry spells. Keep plants well-watered, ensure good air circulation, and apply a dilute potassium bicarbonate spray at first signs.

How to tell chantilly peach snapdragon needs repotting

Repotting on a calendar is less reliable than reading the plant. For chantilly peach snapdragon, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot chantilly peach snapdragon on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot chantilly peach snapdragon

Pot on seedlings as they grow; not a perennial repot. Chantilly Peach snapdragonis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Tall, upright annual (short-lived perennial in zones 8–10).

What size pot to step chantilly peach snapdragon up to

Pot chantilly peach snapdragon on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot chantilly peach snapdragon

Pot chantilly peach snapdragon on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting chantilly peach snapdragon

Pot on before it is root-bound. Check chantilly peach snapdragon regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh fertile, moist but well-drained loam, neutral to slightly acidic at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water chantilly peach snapdragon in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for chantilly peach snapdragon

Chantilly Peach snapdragon wants fertile, moist but well-drained loam, neutral to slightly acidic. Amend sandy or clay soils with well-rotted organic matter before planting. Good drainage is essential to prevent crown rot, but unlike Helichrysum this cultivar benefits from richer, more moisture-retentive conditions. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting chantilly peach snapdragon — frequently asked questions

How often should you repot chantilly peach snapdragon?

Pot on seedlings as they grow; not a perennial repot for chantilly peach snapdragon. Chantilly Peach snapdragon is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, moist but well-drained loam, neutral to slightly acidic so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does chantilly peach snapdragon need?

When is the best time of year to repot chantilly peach snapdragon?

Can you put chantilly peach snapdragon straight into a much bigger pot?

No. Even a fast-growing chantilly peach snapdragon should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise chantilly peach snapdragon after repotting?

Not immediately. Wait about 1 week after repotting chantilly peach snapdragon. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
