This half-hardy annual is ideal for cut flowers, providing plenty of impressive blooms for your home.

  • Unique petals
  • Loved by pollinators
Sowing Indoors
Level fill a tray with seed compost firming with the base of another tray. Water well with a fine rose. Scatter seeds thinly, lightly covering with vermiculite or a little more compost. Place in a propagator at 18-25°C or cover tray with cling film and leave in a warm room.
Growing On
When shoots appear, remove cling film. Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant 5cm apart into small pots
or module trays. Grow on in a minimum temperature of 10°C.
Planting Out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out in full sun when risk of frost has passed. Allow 30cm between plants. Water well until established.
Aftercare
Water well, especially during warm spells. Feed regularly during the flowering season and deadhead faded blooms to keep plants blooming for longer.

How to grow

Sow seeds on to the surface of pre-watered seed compost, but don't cover them. Keep warm, around 20°C and keep moist, but not wet. Allow 1-2 weeks for germination.
