Its compact habit and free flowering make it very useful for edging. The flowers are deep blue with a prettily contrasting white eye. Also valuable for window-boxes and hanging baskets.
Sow late winter to mid spring at 18-24C (65-75F) in a good seed compost. Sow seeds on surface of compost and gently firm down compost. Keep soil damp but not wet. Do not exclude light, sealing in a polythene bag after sowing is help- ful. Germination usually takes 14 to 21 days.
When seedlings are large enough to handle, transplant in bunches of 3 or 4 and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10 to 15 days before planting out after all risk of frost, 10cm (4in) apart in a sunny spot in light moist soil. For pot plants, transplant the seedlings into 7.5cm (3in) pots, grow cool. well ventilated and give plenty of light, but shade from direct sun.
