How to Grow

Seed can be directly sown in the garden in a sunny spot in mid to late May for flowering in the following year. Seed can be started indoors in a soil-less mix 8 weeks before the last frost. Sow seed 3mm (1/8") deep and keep at 21C (70F) for the 10-20 days germination period. After germination, grow on at a slightly cooler temperature before hardening off and transplanting outside to a sunny spot after the danger of frost has passed. Space plants 15cm (6") apart in the garden.
