Germination Information

Pre-treatment: Seeds are scarified by pouring boiling water over them and letting them sit for 24 hours. This is followed by one month of warm moist stratification and four months of cold moist stratification. Seeds are mixed with equal amount of perlite or vermiculite in a Ziploc-style bag or a small Rubbermaid-style container, with a small amount of water added. The mixture is then placed in a room temperature setting for at least 1 month followed by a refrigerator or cold garage (33-42 degrees F) for at least 4 months. Seeds can be cold stored until planted for up to 3 years.

Establishment: Seeds are collected by hand from locally native plants within the eastern central Upper Peninsula. The plant flowers from May to June and seeds are harvested in October. The plant is generally distributed in dunes, sandy bluffs, shores, jack pine woodland, river banks, borders of woods and thickets, rocky openings and outcrops, fields and fencerows.
