Before sowing
Artificial heat not needed and can prevent germination; cold stratification beneficial; seeds remain viable 2-4 years
Sowing
What to expect
Tips
Seeds should be sown as soon as ripe. Do not use artificial heat; patient waiting required. Keep soil consistently moist but not waterlogged. Cold stratification in winter followed by spring warming significantly improves germination. Seeds can germinate 3-4 weeks after warming; variable germination 7-26 weeks possible. Plants require 3-5 years to reach flowering stage.
