Garden Expo

April, Fort Zumwalt Park

At the Garden Expo, experts will provide tips for growing a garden full of veggies and flowers that bloom all season. Boost your home’s curb appeal with live plants and trendy outdoor décor, take home a free shrub or tree sapling while supplies last (one per family), find out all about bees and honey from local beekeepers and get motivated by the O’Fallon Garden Club presentation, “Grow It: A Family-Friendly Presentation on Beginning Gardening.” The Garden Club presentations will be held at 10 a.m. and 11 a.m.  At 9:15 a.m., join in the annual Arbor Day Ceremony led by Mayor Bill Hennessy in planting a maple tree with the assistance of the Twin Chimneys Elementary School Earth Club.

For kids, the event offers creative fun with an upcycled craft and a chance to work off some energy playing an interactive inflatable game, “Catch the Bee.” Other attractions include the St. Charles Model Railroad Club, which will have its scenic, radio-controlled layout on display, free, and Historic Heald Home tours for only $2. Picnic-style fare for purchase will be provided by Giardina’s Gourmet Dogs & More and Jo-Jo’z Frozen Yogurt. Admission and parking are free.


O’Fallon Founders’ Day

May, Fort Zumwalt Park

Celebrate the “good old days” of the late 1800s and bask in O’Fallon’s rich heritage at the City’s annual Founders’ Day. Demonstrations and skills such as basket weaving, rope making, beekeeping and blacksmithing are a main feature of the day. Free hands-on kids’ activities and games include cow milking and cow roping (both simulated), cornhusk doll making and playing checkers. Don Collop’s “Cowboy’s Way of Life Chuck Wagon,” and Professor Farquar and Polecat Annie’s “Great American Medicine Show” will provide entertainment and educational fun, and a trio of acoustic musicians will play old-time music.

Historic Heald Home tours will be available for only $2. Event admission and parking are free, and concessions and handmade goods will be available for purchase. A highlight of Founders’ Day will be the 11 a.m. dedication of Zumwalt’s Fort, a rebuilt War of 1812 family fort which will be open to the public as an interpretive site.
