How to Grow
550 seed/gram Sow seed indoors in a soil-less mix in February or March. Barely cover seed and keep at 18 C (68 F) for the 10-15 day germination period. After germination, grow on under lights at the same temperature then harden off and transplant to the garden in a sunny spot with moist to wet soil. Direct sow outdoors starting in mid-May. Thin seedlings to 30 cm (12″) apart in formal gardens. Plants can be cut back by half in early to mid June. This tends to encourage branching which in turn leads to more flowers and reduces the need for plant support.
