The Preservation Society for Spring Creek Forest will host the 20th Annual Trout Lily Tour on Feb. 23. Tours will begin at 10 a.m. and 1 p.m. Tours are free to the public and begin in the park pavilion at the Spring Creek Forest Preserve, 1770 Holford Road. The Trout Lily is one of the first wildflowers to begin flowering each year. Its natural habitat is found in hardwood bottomland forests that have had very little impact from the built environment. The flowering period is only 2 to 4 weeks long and the entire plant cycle is complete in about 10 weeks. The tour is designed for both novice and advanced naturalist, and is an excellent way to learn more about our local environment. The tour will be held rain or shine, so come prepared for the weather. The Preservation Society for Spring Creek Forest meets the first Tuesday of each month at the North Garland Branch Library, 3845 N. Garland Ave., from 7 to 9 p.m. To learn more about the Society for the Preservation of Spring Creek Forest or about this event, call the Parks and Recreation Department at 972-205-2750 or visit SpringCreekForest.org.
