Seed Information
Seed Collection
Capsules change from green to tan-brown and become brittle when seed is ripe. Cut stalks of capsules, place upside down in paper bag and dry in warm spot. Beat capsules to help release fine red-brown seed. Sieve to clean.
Seed Treatment Method
Storage Stratification at 3-5°C for up to 3 months may improve results. Place seed in a damp medium, lightly covered. Put moist seeds in a plastic bag and store in the fridge.
Seed Treatment Notes
Seed matures 3-5 weeks after flowering. Seed from some areas may have 4-6 months after-ripening period. Stratification at 3-5°C for 3 months may also improve results. Cover the fine seed only lightly as darkness significantly decreases results.

3-4 weeks
