A hardy perennial herb with edible licorice-scented green leaves and spikes of aromatic blue flowers from July to September. Highly attractive to bees and butterflies. Sun. Ht: 60cm (24")
Sow seeds into pots or trays on the surface of moist seed compost, do not cover seed. Place in a propagator or warm place and keep at a constant 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 will usually take 30-90 days. Transplant seedlings when large enough to handle into
7.5cm (3in) pots or trays. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 23-30cm (9-12in) apart.
