How to Grow

125 seed/gram. Sow seed indoors in a soil-less mix in early March for late summer flowering in the first year. Growing medium temperature should be about 20 C (68 F). After germination, grow-on under lights at a cooler temperature of 15 C (60 F) before hardening off and planting out to a sunny site after the danger of frost has passed. Dormant fall seeding in mid October is also a good way to start not only this plant but many other perennials. Late fall seeding allows any dormant seed to be naturally stratified over the winter.
