We evaluated several horticultural cultivars and species of Monarda, a plant genus native to the southeastern United States, to assess landscape performance and ecological value to insect wildlife in Georgia Piedmont and montane habitats. We established two experimental sites, at the State Botanical Garden of Georgia in Athens, and the Georgia Mountain Education and Research Center in Blairsville. Our study included ten taxa of Monarda, representing five cultivars and four valid species. We saw significant differences in phenology, powdery mildew tolerance, flower morphology, nectar production, and insect communities at each site and year with Monarda taxa as the main effect. Differences in flower morphology and nectar production had no detectable impact on pollinators, beneficial insects, or plant pests. Our results demonstrate that floral resources of select Monarda taxa do support local wildlife, including a diversity of insect taxa. We observed variations in horticultural characteristics and performance that highlight the remarkable value of this genus in ornamental landscapes in Georgia.
