Germination Information
Pre-treatment: Mix the seeds with an equal amount of either perlite or vermiculite. Seal mixture in a Ziploc-style bag or a Rubbermaid-style container, proceed with up to two months or more of cold moist stratification in a refrigerator or cold garage or sow the seeds directly outside in spring. Cold store until planted (up to 3 years).
Establishment: Seeds are collected by hand from locally native plants within the eastern central Upper Peninsula. The plant flowers from June to September and seeds are harvested in September and October.
