Keep in mind that they're a tender bulb and need to be dug up and brought in where winters drop below freezing. Dragon Wing Begonia Breeders at Pan American Seed Company crossed an angel-wing begonia with a wax begonia to get an exciting new hybrid called Dragon Wing Begonia. It is ideal for bedding and container gardening, just like its cousin the wax begonia, thriving in both shady and morning sun locations.
Leaves are glossy green and shaped like angel wings.
The plant is covered with large, heavy clusters of dangling flowers in scarlet or pink, all during the summer and all year, if you live where winters are mild. The huge panicles of flowers hanging down make this plant ideal for hanging baskets on the front porch or in large containers. I've seen plants in a large container reach 36 inches tall and wide but because of their profuse flowering and self-cleaning habit they're messy on a lanai or patio. I especially like them planted right in the beds where I don't have to worry about the flower drop. Like other angel wing-type begonias, Dragon Wing produces new shoots called canes from the base of the plant.
