Agastache (P)
Agastache foeniculum
Perennial - Zones 6-9.
Start seed 10- 12 weeks before planting out. Sow 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 acclimatize plants to cooler conditions for a few weeks before planting out after all risk of frost, 23-30cm (9-12in) apart.
