This variety can be started indoors in soil trays or pots in the early spring before planting them outside. The seeds benefit from being sown just under the surface of the soil. Then you should place the pots in plastic bags and refrigerate them for 2 weeks. The seeds will take around 14-35 days to germinate. These prairie plants will do best when transplanted outdoors in the spring. We recommend that you plant them in full sun about 24 inches apart.
