Germination Information

Pre-treatment: Seeds are scarified using a sulfuric acid bath, then immediately imbibed in water for 3 days. After pretreatment, seeds are naturally stratified by fall sowing. Some protocols suggest boiling the seed for 1 minute or mechanical scarification.

Establishment: Seeds are typically collected in the fall and stored. Some protocols suggest using a fungicide and endomycorrhizae. There are regional variations in collection and sowing times, and some protocols suggest different scarification methods.
