Propagation:


Bulbs planted in autumn.


Division in spring.


Seed – needs cold stratification, best sown in September - November.

Seed just covered and stored for 2-4 weeks at 20°C (68°F) and then it‘s moved outside until germination. Germination can be slow, seed may germinate a year later, so it‘s important not to throw it away prematurely. Optimum germination temperature is 5-12°C (40-55°F).
