Ornamental Resource

Native ornamental resources include herbaceous plants, woody plants, and vines, and can be divided into plants for flower beds, cuttings, potting, gardening and landscaping, according to their purposes.

  • For wild herbaceous flowering plants in flower beds, many traditional herbs should be replaced three or four times a year. Thus it is too much of a burden to only replace them with annuals, and it is good idea to use some native perennials. While traditional herbs used in gardening can only grow well in places with good sunlight and drainage, some native plants may grow well in shaded or damp areas, so garden plants for various environments should be developed.
  • Both the development of dwarf species and application of culture techniques using growth controls should be undertaken because most native plant species used for potting purposes grow too high in manure soil. For wild orchids, the collection of diverse wild variants is important in developing more value-added cultivars.
  • As it is a global trend to develop spray-type cutting flowers and background flowers of traditional flowers, there are many candidates among native Korean flowering plants. When research on the post-harvest physiology is supported, many native species can be developed.
  • Although a lot of flowering trees and shrubs are used for landscaping, selection improvement is still poor, and it is an area that requires a breeder's efforts. The application of native plants has recently been expanded for the development of native resources for lawns, landscaping, and improvement of water on riverside land.

Major ornamental resources
