Northwestern Yunnan is situated in the southern part of the Hengduan Mountains, which is a complex and varied natural environment. Consequently, this region supports a great diversity of endemic plants. Using field investigation in combination with analysis of relevant literature and available data, this paper presents a regional ethnobotanical study of this area. Results indicated that northwestern Yunnan has an abundance of wild ornamental plants: this study identified 262 endemic species (belonging to 64 genera and 28 families) with potential ornamental value. The distinguishing features of these wild plants, their characteristics and habitats are analyzed; the ornamental potential of most plants stems from their wildflowers, but some species also have ornamental fruits and foliage. Among the endemic genera, Pedicularis and Rhododendron have particularly high numbers of ornamental wild species, while Aconitum, Gentiana, Corydalis, Silene, Delphinium, Cremanthodium, and Saussurea also contain significant numbers of wild ornamental species. It is suggested that cultivation of these species may be beneficial, both commercially and to help conserve endangered endemic plant species.
