How to Grow
270 seed/gram. An easy to grow perennial that can be started early indoors in a soil-less mix March 1st. Sow seed then moisten the growing medium and place the container in a refrigerator for 45-60 days before bringing the container back into the warmth. Keep at 20 C (70 F) for the 10-15 day germination period. After that grow on under lights at the same temperature before hardening off and transplanting outside to a sunny site with moist rich soil. Seed can also be directly garden sown in early May or better still in late fall from mid October through mid November. Late season sowing is beneficial as this allows dormant seed to be naturally stratified over the winter.
