How to Grow
6,350 seed/gram. Due to seed dormancy caused by a hard seed coat, seed is best sown outdoors in the fall. This allows the seed to be naturally stratified during the winter. Indoors, start seed in early March using a soil-less mix. Before sowing, first gently nick the seed coat with a knife or rub it lightly with sandpaper. Alternately, press seeds into the growing medium (as they need light to germinate, the seeds need to be at the surface) moisten, then place the container in a refrigerator or freezer for 4 weeks before bringing the container back into the warmth. Germinate at 15 C (60 F) for 21-30 days then after germination, grow on under lights at the same temperature before hardening off and transplanting outside to a sunny spot with moist soil.
