Technically, forbs are flowering, nongrassy “herbaceous” plants, which means they produce seeds and have stems and leaves that die back at the end of each growing season (versus woody plants, whose stems remain year after year).
Informally, forbs are what most forest preserve visitors call wildflowers. Over 600 different species grow in DuPage County forest preserves, from trilliums and spring beauties to compass plants and coneflowers.
