Begonias are bushy, full and low-growing flowers that are perfect for semi-shady areas and hanging baskets. Most varieties available today to homeowners are hybrids with complex parentage from original varieties found in southern Africa and South America. The most popular types also have tuberous roots rising to reddish stems with bright green, waxy foliage and clusters of bright flowers and are propagated from leaf or leaf-chip cuttings. Caring for hybrid begonias is the same as caring for original varieties.
