How to Grow

140 to 180 seeds per gram. Naturally stratify seed by sowing directly outdoors in the fall in a sunny site – cover seed very lightly with soil. Indoors sow seed in a soil-less medium in early February, barely cover seed as diffuse light aids germination. Stratify seed by placing container in a refrigerator or other cold place for 3 months. Bring the container out and keep at 20 C (70 F) for the 10-18 day germination period. Grow on under lights at a slightly cooler temperature before hardening off and transplanting outside after the danger of frost has passed. Plants grow 60-120 cm (2-4′) tall. Seed from mature plants disperses easily by wind action.
