Cultivation

 

For best results, expose seeds to moist, cold conditions (stratification) prior to sowing. For cold stratification, place seeds in moist potting soil or sand and store in a refrigerator for 4-6 weeks. After stratification, sow seeds in containers or direct seed outdoors after the danger of frost has passed. Sow seeds 1/8-1/4" deep and 6-8" apart. Optimal soil temperature for germination is 65-80˚F. Seeds will sprout in 10-28 days. Thin seedlings so that mature plants are 24-36" apart.

Seeds can also be direct sown outdoors in the fall where they will stratify naturally and germinate the following spring.
