800 seeds/gram. For best results chill seed for 3 to 4 weeks at 5 C (40 F) prior to sowing. Start early indoors in a soil-less mix. Keep at 20-22 C (70-75 F) for the 21-25 day germination period then grow on under lights at a cooler temperature before hardening off and transplanting outside. Seed can also be sown directly into the garden in June or again in August and early September for bloom the following year. Do not cover seed as light is beneficial for germination. Columbine prefers moist soil in light shade but will tolerate full sun except for hot, dry areas. Plant 30-45 cm (12-18") apart, feed monthly and keep well watered.

Some perennial plants produce seed that is viable but dormant. This means that while the seed has all the internal structures and nutrients required to germinate, the seed coat is so hard, water cannot pass through it and initiate germination. When seed is in this state, it is known as being dormant. Seed dormancy is a naturally selected for trait that protects the seed of many plants allowing them to safely overwinter and then be ready to sprout in more favourable conditions in spring.
The remedy to naturally breaking seed dormancy is typically the passing of time. In particular, seed overwintering outside and experiencing the natural freeze thaw cycles that occur in late fall, winter and early spring. To artificially break seed dormancy, sow the seed in a soil-less mix, water than chill in a refrigerator. This dormancy breaking process is called stratification.
