Flowering

Flowering
  • Half hardy annual
  • Unusual, quill-like petals
  • Long flowering season
  • Excellent in borders, with soft, fern-like foliage; also ideal for cutting

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.
