Some American Native Wildflower seeds need to go through a cold winter to germinate. This plant is one of them. They do this so the seed won’t sprout in fall, only to have the seedling not make it through a cold winter. I have stratified these seeds to simulate a cold winter(stratification) This raises the germination rate considerably. Thanks for looking!! Vernonia fasciculata. Perennial. Full Sun.
