Tuberous begonias (Begonia × tuberhybrida Voss, known as the Tuberhybrida Group or the Tuberosa Group) are a group of Begonia cultivars, sometimes regarded as some of the most spectacular of the genus. One of the first hybrids produced was in 1870.
Types of tuberous begonias include upright or trailing varieties. Tuberous begonias are popular for their beautiful flowers that come in a variety of colors and forms. Red, orange, yellow, white, salmon and pink blooms may be single or double and may be plain, ruffled or toothed. Their petals may have margins, crests or blotches of contrasting color. Tuberous begonias bloom throughout the summer, thriving in shady spots where few other plants with long bloom periods and showy flowers can grow. They are often used as container plants on patios and porches, in hanging baskets, and as bedding plants. Tuberous begonia species are native to tropical South America and southern Africa.
