Seed To Bloom:
A stratification period is beneficial but not required for germination. Sow in a container, cover with a plastic bag and refrigerate, or mix seed with damp clean sand or vermiculite, bag, and refrigerate at 35-40F. Bring out of chill after 30 days and keep at 65-75F.
Direct sow in fall or earliest spring, or wintersow into pots in the shade, covered with a thin layer of clean sand and a wire screen to keep out mice and voles. Check for water, keeping evenly moist.
