I use a lot of begonias in my clients’ container gardens during the summer. Some are used for foliage, while others are used for a proliferation of flowers. Rex begonias have beautiful symmetrical leaf patterns and insignificant flowers, while cane begonias produce long branching arms, dripping with flowers for months on end. Tuberous begonias come in summer-hot sizzling colors like tangerine-orange and ruby-red. These are all shade plants, especially here in Zone 7B, but they stand up to the heat very well.
Look for the different types of begonias in the garden center. My favorites include Tuberous Begonias, Shrub Begonias, Rex Begonias, and Rhizome Begonias, all of which offer a stunning variety in foliage and flower production.
