This variety can be started indoors in soil trays or pots 6-8 weeks before planting them outside. You can sow the seeds just under the surface of the soil and they will take around 5-21 days to germinate. These prairie plants will do best when transplanted outdoors after the danger of frost has passed. Plant them into poor soil lacking in minerals - otherwise the stems will become weak. We recommend that you plant them in full sun to partial shade about 12-18 inches apart.
