Sowing
What to expect
Tips
Sow seeds in spring on surface or barely covered. Maintain consistent moisture and provide bright, indirect light. Small bulbs form before winter dormancy. Plants flower in their third or fourth year from seed. Seeds have a 6-month viability period and should be refrigerated for storage. Keep soil well-drained to prevent rot.
