This variety requires double dormancy and can take anywhere from 30 days to 2 years to germinate.
Transplant: Starting 4 months before you plan to put them in the ground, expose seeds to 21C/ 70°F for two weeks, then 4C /40°F for three months. In the spring, when the second set of leaves appears, transplant outdoors. Harden plants off for one week. Transplant to partial or full-shade location, 2 inches apart.
Direct Seed: Sow at 1/4" depth. Plant seeds in late fall. Nature will take care of the cold stratifying required and the seeds will go through the temperature cycle required for germination. It may be two springs away before they germinate.
