Germination Information
Pre-treatment: Seeds are soaked in water for 1 to 4 hours, then placed on moist paper towels inside an opened plastic bag and refrigerated at 1 to 3 C for 30 days. Seeds are then surface sown on the medium.
Establishment: Seeds are hand collected in early to late fall when capsules turn brown and are just beginning to split open at the top of the capsule. Seeds are kept in paper bags in a well ventilated drying shed prior to cleaning. H. formosum occurs in coastal to subalpine habitats, from B.C. to Baja California, east to Montana, Wyoming, and south to Mexico.
