To propagate Spring Beauty, the most common method is by sowing seeds in the fall, as they readily spread through self-seeding, or by planting small tubers (also called corms) in the autumn, which are the plant’s underground storage structures; collect seeds when they turn black on the seed pods and sow them immediately for best results. 

Key points about propagating Spring Beauty:
