The above propagation data sourced from Claude AI
Pre-treatment: Field seed is sown in the fall, after cleaning, therefore it does not require cold storage. If weather does not permit fall planting, store the seed dry, in cold storage at 34-36 degrees. Field sown seed is not damp stratified due to clumping problems during the drilling process.
Establishment: Seed is collected by a custom designed combine from nursery stock. The plant flowers from approx. July 15 to August 28. Seed is harvested about Sept. 23. L. spicata is found throughout the eastern third portion of the United States.
