Establishment: Seed is collected in September when the inflorescence is dry and the seeds are brown in color. Seed can be stripped from the stalks by hand or entire stalks can be cut. Plants hold their seed well, shattering is not generally a problem. Harvested seed is stored in paper bags at room temperature until cleaned. There is some conflicting information about whether cold, moist stratification improves germination rates.
