Angelonia are heat-loving plants that will grow most vigorously and bloom best when the heat is on. They are plants best planted in mid-spring or later, since they won’t really grow until the temperatures warm up. Angelonia will tolerate wet feet and a fair amount of drought. The plants are easy care with no deadheading needed. A bit of fertilizer or some compost in a garden bed is usually all that is needed for these plants to thrive. Due to their heat-loving nature they are one of the plants that can be planted even during the heat of mid-summer.
