The area in front of Janet and Jeffrey Crouch’s house in Columbia, Maryland, does not look usual for their neighborhood. That is because the Crouches do not have a grass lawn. Instead, they have some small trees and many native plants. Lawns are areas around a house or in a park that are covered with short grass. In recent years, support for replacing lawns with native plants has been increasing in the United States. The process is called rewilding. In fact, the number of Americans planning to turn part of their lawn to native wildflowers doubled between 2019 and 2021. That information comes from the National Gardening Survey of 2,061 U.S. adults. In 2019, the percentage was nine percent. By 2021, it rose to 19 percent.
