Begonias are found wild in South and Central America and many are native to India and other tropical countries. Begonias are grouped into seven classifications: Cane-stemmed, Rex-cultorum, Rhizomatous, Semperflorens, Shrub, Tuberous, Winter-flowering.
All Begonias need light, well-drained soil that is neutral or slightly acidic. They need bright, but indirect sunlight. They need more water when they are growing actively, less when they are not. In late spring and early summer, they should be given fertilizer with every watering. They should be repotted every spring. Tuberous Begonias can be started in early spring by setting tubers into shallow flats. Begonias that form rhizomes can be cut into several pieces in early spring and potted separately.
