Angel wing begonia can reach a height of 24 inches (60 cm). With careful care, a bush can reach a height of 40 inches (1 m). Begonia corallina spreads widely, which frequently happens if you don't provide vertical support for its stems. This kind of begonias is one of the most rapidly growing.
The stems of this begonia are usually straight, but they might bend slightly under the weight of the leaves. One rhizome can produce a large number of shoots. They develop and grow quickly. The stems are naked and have obvious marks from the point where the leaf petiole meets the shoot.
