Pre-treatment: Mix seeds with sand and sow directly into target containers with a growing medium of 40:20:20:20 peat:composted fir bark:perlite:pumice. Add Nutricote controlled release fertilizer at the rate of 0.5 gram per 107 ml container. Seal racks inside plastic bags and refrigerate at 1 to 3 °C for 30 days. Alternatively, seeds can be cold stratified for 150 days.
Establishment: Seed ripens in July or August and can be collected from wet forest road ditches. Access can be difficult along streams or in denser, swampy brush where the species is commonly found. The plant is widespread across North America, including the whole United States and the Western half of Canada.
