Rhododendron
Rhododendron (; pl.: rhododendra), from Ancient Greek ῥόδον (rhódon), meaning "rose", and δένδρον (déndron), meaning "tree", is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia.
Various species of Rhododendron are the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland and Himachal Pradesh in India, the provincial flower of Jeju Province in South Korea and Jiangxi in China, and the state tree of Sikkim and Uttarakhand in India. Most species have brightly coloured flowers which bloom from late winter through to early summer.
