Germination
Sow indoors. Sow seed onto moist well-drained seed compost. Just cover with a fine layer of vermiculite. Propagate +20°C. Keep soil moist but not wet. Germination takes 10-15 days. Transplant seedlings when large enough to handle to 8cm pots. Grow on in cooler conditions. Acclimatise and plant out after danger of frost has passed with 45cm spacing. Can be sown directly from late April. Sow thinly 3mm deep into well prepared soil which has been raked to a fine tilth. Water regularly. When large enough to handle thin to 45cm spacing.
Growing
Prefers a moist well-drained soil in full sun. Do not allow soil to dry out. Mulch if soil is prone to drying out.
Cultivation
Deadhead regularly to extend flowering and encourage further blooms. Deadhead if you do not wish to self-seed.
