The angel wing begonia plant, named for the contour of its leaves that resemble the wings of angels, originated in South America. Foliage and blossoms grow from elevated, bamboo-like stems, explaining why this plant is also referred to as cane begonia.
Angel wing begonia foliage unfurls to reveal either mahogany-colored leaves or those of pale to deep green that often contain white or silver spots. The appearance of yellow rings on leaves indicates leaf spot — bacteria that thrive in a cool, moist environment. According to the Guide to Houseplants, removing affected leaves and keeping the plant away from air conditioning and heating vents should alleviate the problem.
Angel wing begonia plants produce blossoms that form delicate, dangling clusters of white, pink and red. Most bloom in spring and summer, but some flower year-round, according to South Carolina’s Clemson University Cooperative Extension.
Bright, indirect light allows for an abundance of blossoms and vivid leaf color. Excessive watering causes the elegant angel-winged leaves to turn yellow and fall from the plant. If not pruned, an angel wing begonia plant can grow to a height of 10 feet, reports Clemson University.
