Germination Information
Pre-treatment: Seeds can be placed in 0-1°C (32-34°F) for a 10-day cold stratification treatment and then exposed to 22-25°C (72-77°F). Alternatively, fresh seed should be stratified or dry stored for 6 months prior to sowing. Some protocols suggest no pre-treatment is required.
Establishment: There is variation in the pre-treatment protocols, with some suggesting cold stratification or dry storage, while others suggest no pre-treatment is required. The germination rate was not provided in the protocols. Collection of seeds varies, with some protocols suggesting collection when the inflorescence begins to dry and the seed is in the soft to hard dough stage but before it shatters from the inflorescence.
