To germinate the seeds: Fall plant seeds before winter and cover with 1/4 inch sandy soil inch. Space seeds about 1 inch apart in the row. Seeds will germinate in the spring. Seedlings are quite frost resistant so not to worry for most frosts. For refrigeration, store at 33-38 F in lightly moist Canadian peat moss for 90-120 days. Seeds will begin to sprout after 60-80 days. Lightly cover the seeds if you are growing them in pots so to avoid damping off.
