The above propagation data sourced from Claude AI
Pre-treatment: Requires stratification: mix the seeds with an equal amount of either perlite or vermiculite. Seal mixture into a Ziploc-style bag or a Rubbermaid-style container place in a cool dry place (refrigerator or cold garage) 1-3 months. Cold store until planted (up to 3 years).
Establishment: Seeds are collected by hand from locally native plants within the eastern central Upper Peninsula. The plant flowers from July through September and the seeds are harvested in October through November. The plant is generally found in river banks and floodplains, thickets, low woods, swamps, including cedar, wet ditches in or by woods, marshy ground.
