Care Information

  • Sow indoors, January-April. A warm kitchen windowsill is all you need for starting these seeds.
  • Sow thinly on the surface of a small tray of pre-watered compost. Place in a warm, light position. A temperature of 15-20C (60-68F) is ideal. Keep the compost moist. Seedlings appear in 14-21 days.
  • Transplant them, in tiny clumps, 5cm (2in) apart, to other trays when large enough to handle. Grow on in cooler conditions.
  • Gradually accustom young plants to outside conditions (avoid frosts), before planting out, May-June, 15cm (6in) apart, into well-drained soil, when frosts are over.
  • Lightly trim back the plants after the first flush of flowers to encourage further flowering.
  • Flowers: June-October.
