Surface sow; press into soil.
Recommended. Start indoors in late winter. Cover with a humidity dome or a light sprinkling of vermiculite to retain humidity until germination occurs. Keep at 70F. Alternately, while not essential, a cold, moist stratification period may increase germination. Sow in pots, cover with plastic, refrigerate at 36-40°F for 3-4 weeks, then bring into 70°F.
Not recommended, as seeds and new seedlings are very tiny and delicate. Possible to wintersow in late winter into pots placed in full shaded conditions and covered with a wire screen to keep out mice and voles. Check for water as needed.
