This is a very large genus with about 1,400 species of plants native to many subtropical and tropical regions of the world.

Traditionally, begonias have been divided into about 3 categories. 1) Tuberous begonias are generally used in containers and hanging baskets especially in shaded areas. 2) Rex begonias are grown for their foliage and tend to be non-hardy for outdoor use except in tropical or subtropical areas. 3) In relatively recent decades, a type called "seed begonias" has taken off in popularity. They can be easily grown in large groupings and do quite well in full sun if watered properly.
