This site is created to help residents east of the Rockies or in mountain parks to select plants that are most likely to grow in these particularly tough environments.
Wind, challenging soil conditions, high elevation, strong sunlight, exposed areas, winter blizzards, and summer droughts are some of the conditions that plants recommended here have met and survived.
Check the "About Plants for Prairies" page and the front page of the primary blog (which may or may not still be called Blog A) for additional background information.
