How to Grow
350 seed/gram. Sow directly outdoors or 10 weeks early indoors for early summer flowering the first year. Sow outdoors anytime April to June and again in late August and early September for flower in the following year. Thin seedlings to 30 cm (12″) apart in the garden. Self-seeds very easily when established. Divide older plants every 3 to 4 years. If starting indoors, use a soil-less mix and keep seed at 21 C (70 F). After germination, grow-on under lights at a cooler temperature of 12 C (50 F). After hardening off, transplant outdoors to a fully sunny spot after the danger of frost has passed.
