This variety can be started in soil trays or pots 6-8 weeks before planting them outside. The seeds benefit from being sown just under the surface of the soil. The seeds will take around 30-90 days to germinate. These prairie plants will do best when transplanted outdoors after the danger of frost has passed or directly sown into the soil as soon as it can be worked in the spring. We recommend that you plant them in full sun to partial shade about 12 inches apart.
