Germination Information
Pre-treatment: Seal the seeds in a bag or container with an equal mix of seeds and perlite or vermiculite. Add just enough water to barely saturate the mixture and store in a refrigerator or cold garage (42 degrees F) for at least 2 months. Cold store until planted (up to 3 years). Seeds are also warm and cold stratified.
Establishment: Seed is collected by hand from locally native plants within the eastern central Upper Peninsula of Michigan. The plant has a strong licorice odor when bruised. O. longistylis is found within temperate deciduous forests of North America.
