Ennis was designated by the 1997 State Legislature as the home of the "Official Texas Bluebonnet Trail" and was designated the "Official Bluebonnet City of Texas.". From April 1-30, Ennis showcases over 40 miles of mapped driving Bluebonnet Trails sponsored by the Ennis Garden Club. These trails are the oldest such trails known in the state, and tens of thousands of visitors make the short trek to Ennis to view this wonderful wildflower show. The Ennis Garden Club will drive the trails to check the bloom status each week starting in April. The Club then reports to the Ennis Convention and Visitors Bureau about the latest status of the bluebonnets so that visitors can be well informed where the best flowers are on the trails at the time of their visit. Each year, the bluebonnets will appear on different trails as these are natural to the area. In Ennis, the bluebonnets typically peak around the 3rd week of April, according to the Ennis Garden Club.
