A neat, dwarf, bushy, habit, with large dense blue flower spikes, over a very long period. Quick to flower in 12-16 weeks from an April sowing. Ideal for borders and containers.

Height: 30-40cm (12-16in).

Sowing Time: February to June or September to October. Sow into pots or trays of moist seed compost and cover seed with a fine sprinkling of compost or vermiculite. Keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination usually takes 7-21 days.

When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 23-30cm (9-12in) apart. For best results, provide any ordinary, well-drained soil in full sun.
