dancingcat Posted June 9, 2022 Author Share Posted June 9, 2022 ty @colinbm Most of our native tallgrass prairies in the central USA are gone now, either plowed or paved over. But we do have remnants of native prairie grasslands protected by various conservation organizations, where we get fabulous displays of wildflowers every spring. My family's land also has some pasture land that's never been plowed, just used for horses, so that's a source of good flowers too. In the 1800s when most of the prairie flowers were described by botanists, it must have been spectacular. Link to comment
