The Master Gardener program is a volunteer horticultural training and an educational outreach program developed and managed by state cooperative extension services. Previous research in the southeastern United States revealed that landscape architects and contractors are increasingly using native plant materials in their projects and this often exceeds regional plant availability. A survey of green industry in the region showed supply is driven by consumer demand and education. To determine if native plant demand is encountered by plant purchasers other than landscape architects, this study evaluates the interest level and market use of native plants by Master Gardeners of six southeastern states. A web-based survey was developed, and Master Gardeners were invited to participate by their state Master Gardener coordinators. The survey included questions on how Master Gardeners use native plants in their home landscape, how they best learn about them, the species they have purchased, and their interest level. A total of 979 Master Gardeners completed the survey. Results revealed that this particular consumer group is enthusiastic about native plants and supports the landscape professionals' claims that marketing for native plants could improve if plants were available at more retail outlets, by having more types (herbaceous plants, shrubs, and trees) and species for sale, and by offering greater quantities of plants.
