Plant Class: Half Hardy Annual (HHA)
Habit: Bushy, Upright
Early/Late Flowering:
Indoor growing instructions In trays of seed compost. Sow thinly and cover with a fine layer of compost. Firm gently and keep moist. Keep at approx. 15-20°C. Germination takes 14-21 days. Grow on at approx. 13-15°C. When large enough transplant 5cm apart in trays. Acclimatise plants to outdoor temperatures from late May and transplant 30cm apart in flowering position. Keep moist and weed free.
Outdoor growing instructions Directly into prepared soil in final flowering position. Sow thinly in rows 30cm apart and cover with a fine layer of soil. Firm gently and keep moist. When large enough thin to 30cm apart. Keep moist and weed free.
Tip Will do well even on relatively poor soils. Deadhead regularly to prolong flowering.
