Snapdragon (Angelonia)

Angelonia, often called summer snapdragon, is a warm-season flowering plant with upright stems and narrow green leaves. It is treated as a tender perennial in warm climates and commonly planted as an annual where winters are cold, bringing steady summer color to sunny beds and containers. ## Growth and flowering The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/angelonia-angustifolia/) describes *Angelonia angustifolia* as an upright, somewhat bushy plant that can sprawl without staking, with long summer flowering and no need for routine deadheading. It reports typical height around 12–18 inches, consistent with the catalog’s current height. [UF/IFAS Extension](https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/angelonia/) notes that flower colors vary among cultivars, including white, pink, lavender, and purple; because this catalog entry is generic, no single flower color is assigned. Plants perform in full sun and warm conditions. ## Site and seasonal use Use angelonia in sunny borders, repeated groups, or containers. Give it moist but well-drained soil during active growth. Established plants can tolerate some dry spells, and both NCSU and UF/IFAS describe good heat performance; new plantings still need regular water while roots develop. Angelonia is perennial in frost-free or mild regions but is usually handled as a bedding annual in colder areas. The catalog keeps its existing USDA zone values and generic identity rather than inferring a particular species or cultivar from the common names. ## Maintenance Remove damaged stems as needed, but routine deadheading is unnecessary for the species described by NCSU. Watch for aphids and powdery mildew, especially when airflow is poor or foliage stays wet. Replace plants after frost where they are not winter hardy.
