A generation ago it was said that to plant a prairie you start by planting a “matrix” of rough and tough native plants to make the soil ready for the more finicky plant species to be added years later. These finicky, or conservative, species might be plants like birdsfoot violet, lead plant, pussytoes, shooting star, and many others. The rough and tough might be plants like indian grass, bee balm, yellow coneflower, and big bluestem.
We have found we can plant all species on year one.
Photo below is one of dozens of pasque flower on a gravelly prairie planting that have been doing well for a quarter century:
