| Abstract:
Hunan (China) is located in transition zone between subtropical and temperate forests with mild temperature and sufficient rainfall. The special locality and variable topography enrich the diversity of plant species. More than 5,500 taxa of vascular plants have been documented. Since no plant exploration in Hunan occurred for the purpose of ornamental plants, we have studied its ornamental plant potential in recent years. By comparing with cultivated ornamental plants in Asia, Europe, and North America, Hunan has more than 2,000 native plants that can be introduced and cultivated as ornamental plants. Some endemic species to Hunan, such as red loropetalum, already brought to the worldwide attention in the ornamental field. Others, such as red-flower Mulian and Dong-an Tea, have great ornamental potential and for their breeding. The distinguishable ornamental groups, such as native fern (about 300 species), conifers (46 species), camellia (33), holly (63), magnolia (31), orchid (66), and rhododendron (46), had been addressed at species level. The potential for further breeding work and cold hardiness had been investigated. This study will enhance the plant exploration and utilization for Hunan and bring more beautiful plants in our daily gardens. | |
