About the Trial
The Cincinnati Zoo & Botanical Garden horticultural staff and volunteers, in conjunction with several other organizations, conducts plant trials on annuals, grasses, and perennials in accordance with regimented protocols. Such trials enable them to develop useful data for gardeners, other public gardens, plant producers, and others in the green community. For more information regarding their Plant Trials programs, please contact horticulture@cincinnatizoo.org.
