Plant Trials Symposium

The Cincinnati Zoo & Botanical Garden’s Plant Trials Day Symposium is a fun and upbeat day dedicated to the very best plants for gardens and landscapes. For fourteen years, we have brought to Cincinnati the very best plant experts from around the country. Our past speaker list reads like a who’s who of American horticulture, and we continue to build on it! An educational and inspirational day for green industry professionals and gardeners. A very popular event that sells out every year. Register early!
