Germination Information
Pre-treatment: Seeds require extended cold, moist stratification. Soak seeds in water for 24 hours, then place in a germinator at 4°C (39.2°F) in the dark for a 60-day prechill. Alternatively, seeds can be sown in containers in November and left outside under cool, fluctuating spring temperatures.
Establishment: Above ground growth is slow as the plants expend energy developing a substantial taproot. Plants grow in early spring and go dormant in mid-summer. In the first year, most plants will only produce a few leaves. Seed collection varies, with some protocols suggesting collection in late June or early July, and others suggesting July or August. Seed ripening is uniform within each individual umbel, but less so between umbels on the same or different plants.
