Built in 1987, our 18,500-square-foot building houses propagation and production for three seasons of annuals and perennials. The fourth season is devoted to Cantigny’s holiday poinsettia crop.

About a quarter-million plants cycle through the greenhouse every year, and more than 1,000 varieties. The plants add color and botanical diversity throughout the park and golf course. In addition, plants are offered for sale at the Cantigny Shop inside the Visitors Center.

The greenhouse opens for public tours several times each year, such as the Shades of Crimson poinsettia display and sale in November. Check the event calendar for details.
