Pre-treatment: Seal the seeds in a bag or container in equal amounts of seeds to perlite or vermiculite and add just enough water to moisten the entire mixture. Store in a refrigerator or cold garage (42 degrees F or colder) for at least three months. Cold store until planted (up to 3 years).
Establishment: Seed is collected by hand from locally native plants within the eastern central Upper Peninsula. Flowers from May-July. Seed is black, globular, pitted and is harvested in August-September.
