Germination Information

Pre-treatment: One month of moist cold stratification is required. Use a Ziploc-style bag or a small Rubbermaid-style container to mix an equal amount of seeds with either perlite or vermiculite. Add a small amount of water. Place in a refrigerator or cold garage (33-42 degrees F) for at least one month. Cold store until planted (up to 3 years).

Establishment: The plant is found in the eastern half of the United States and likes dry to sterile or rocky soils. It is particularly common on jack pine plains, where it may form a solid carpet after disturbance, occasionally found in marshy or boggy places. Seed is collected by hand from locally native plants within the eastern central Upper Peninsula or in Acadia National Park, Maine.
