Cultivar Trial Gardens

The Cultivar Trial Gardens, located at The Ohio State University Chadwick Arboretum & Learning Gardens, are conducted each year in order to evaluate ornamental bedding plants. The objective of these trials is to observe the performance of the plants under environmental conditions typical of central Ohio, as well as to determine local consumer preference for each plant.


Though the Cultivar Trials were paused due to COVID in 2020, Pamela Bennett, Associate Professor with The Ohio State University, State Master Gardener Volunteer Program Director and Horticulture Educator for OSU Extension in Clark County, and Interim Program Director for Chadwick Arboretum has begun making preparations for a brilliant showcase in 2021 of cultivars. They will be evaluated  throughout the summer by staff, students, and volunteers for performance and consumer appeal. 

The trial gardens are always open to the public and are a favorite place to visit with beautiful color throughout the growing season. Planting takes place in May and plants are removed in October. Chadwick Arboretum volunteers help with preparing and planting the gardens as well as evaluating the plants.
