- Notes:

Pre-treatment: Seeds are placed in cold moist stratification during winter months or dry stored for spring germination. No treatment is also an option.
Establishment: Seed is collected by hand from locally native plants within the eastern central Upper Peninsula. Germination occurs the following spring. The greenhouse holds plants at all stages of growth so the temperature setting stays the same for all plants at all stages of growth.
