2. Azaleas: The azalea species Rhododendron hongkongense was discovered in Hong Kong in 1851 but was mistaken for another, only acquiring its Hongkong name in 1930. The species, which is found only on Ma On Shan and a few nearby sites, blooms in April with colours ranging from white to light red. Since 2006, an annual Ma On Shan Azalea Festival has promoted the azalea as the symbol of the district, celebrating six locally native species: (Rhododendron championae, Rhododendron farrerae, Rhododendron hongkongense, Rhododendron moulmainense, Rhododendron simiarum and Rhododendron simsii) Various activities are held, including planting azaleas in housing estates and greenery areas, a photo-taking competition, painting competition, and exhibitions. The event is organised by Sha Tin East Area Committee of the District Council, Sha Tin District Office, Civil Engineering and Development Department, Leisure and Cultural Services Department, Ma On Shan Promotion of Livelihood and Recreation Association, the MTRC and various other bodies.
