Cedar is one of the world's famous ornamental garden tree species, with strong dust-proof, noise-reducing and sterilizing abilities, and it is also suitable as a greening tree species for industrial and mining enterprises. The tree is tall with a beautiful shape, most suitable for being planted as a solitary specimen in the center of a lawn, in the center of a building's front courtyard, in the center of a square, or on both sides of major buildings and at garden gate entrances. The large branches on the lower part of the trunk spread out flat from near the ground and do not wither for many years, forming a lush and majestic crown. In addition, planted in rows on both sides of a garden path to form an avenue, it is also extremely spectacular.
