Germination Information
Pre-treatment: Seeds are placed in cold moist stratification for 150 days. If unable to plant in the fall due to weather, store the seed dry in cold storage at 34-36 degrees F. Field seed is not damp stratified due to clumping problems during the drilling process.
Establishment: The plant flowers from approx. May 12 to July 30. Seed is harvested about August 12. P. integrifolium is found from the eastern United States west to Kansas and southern Missouri. It occupies open wooded sites.
