Angelonia is adapted to hot, humid summer conditions; in cold-winter areas it is usually grown as an annual, while frost-free or mild climates can support perennial growth. ## Maintenance Keep plants watered while establishing and during long dry spells. Deadheading is not normally required. Watch for aphids and powdery mildew where plants are crowded or air movement is poor.
