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 last frost. Sow seed 3 mm (1/8″) deep and keep at 21 C (70 F) for the 10-20 day 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 15 cm (6″) apart in the garden.
