Rhododendrons are among the most beautiful and fascinating flowering shrubs. Native to the forests of China, India, Nepal, and the Himalayas, rhododendrons represent the largest genus of shrubs in the world (about 1,100 species) and come in a wide array of shapes, sizes, and colors.
Rhododendrons and azaleas are one of the most popular plants in the world. They grow in all continents except Antarctica. These plants are members of a large family known as Ericaceae, which also includes blueberries, cranberries, heathers, and several types of vines.
