Angelonias are not well-known outside of gardening enthusiasts. But that could change, as the summer heat continues to grip most of the U.S. Angelonias (Angelonia angustifolia) – also called summer snapdragons – are a hardy flowering plant that can survive the hottest temperatures. In fact, they seem to crave the sun. The stalks of these annuals boast a spiky, upright posture and can reach heights of 2 feet; they produce purple, pink or white blooms and have a smell akin to apples. They’re native to México and the West Indies and can be planted in almost any type of soil, including clay. Photos courtesy of Ball Horticultural Company.
