Mystery Irises
The Rivers of Iris exhibit at the Coastal Georgia Botanical Gardens (CGBG) is flourishing, but the technicolor blooms aren’t the only things attracting attention. Stan Gray, volunteer iris curator at CGBG, and Brian Shamblin, an associate research scientist with the University of Georgia’s Warnell School of Forestry and Natural Resources, are growing several mystery irises at the gardens that could prove to be one of two exceptionally rare iris species: Iris rivularis or a variant of Iris hexagona.
