Tuberous (Rieger) begonias are prized for their big leaves and big, bright rose-shaped flowers. These plants can be used indoors in bright indirect light or outdoors in a shaded or partly sunny location. Rieger begonias are happy with a little sun in the morning, but should not be exposed to hot mid-day/afternoon sun. These begonias area easy to care for; no deadheading is necessary. They are sold in hanging baskets, but the hanger is easily removed if you wish to place them on the ground or a table. Water regularly, but it is important to let the soil dry a little between waterings. These begonias can develop stem or root rot if the soil is kept soggy for too long.
