Propagation. From there, you can refer to the Native Plant Propagation page on our website. Here you will find various ways to sow seeds, including scattering them during a snowstorm, creating mini-greenhouses out of Ziplock bags (be sure to view the fabulous how-to video by member Jen Frazer!), and sowing them outdoors in trays. Just pick a method that feels do-able for you, and treat it as a fun science experiment.
