Guardian Angel Blue Summer Snapdragon

Guardian Angel Blue is an upright, blue-flowered Angelonia for warm-season borders and containers. Its narrow green foliage and long flower spikes bring vertical color through hot weather, while the compact habit works well in groups or mixed plantings. ## Form and placement [Ball FloraPlant identifies Guardian Angel Blue as cultivar ‘Balguaralue’](https://www.ballseed.com/Legal/PlantProtection); nursery listings give a mature height of 14–18 inches and a spread of 10–14 inches. Use it near the front or middle of a sunny annual bed, or in a container where the upright flower spikes can be seen. Leave a little extra room because final size can vary with growing conditions. ## Siting Give the plant [full sun and warm weather](https://plants.ces.ncsu.edu/plants/angelonia-angustifolia/). Angelonia grows best in fertile, well-drained soil that stays reasonably moist; [established plants can tolerate some dry periods](https://gardeningsolutions.ifas.ufl.edu/plants/ornamentals/angelonia/). It is commonly grown as a summer annual, though it may persist as a perennial in frost-free climates. The flower color and upright habit are specific to Guardian Angel Blue; general Angelonia guidance informs its siting and care. ## Maintenance Plant after cold weather has passed and water regularly while roots establish. Once established, adjust irrigation to heat and soil drainage. Avoid excessive fertilizer, which can favor foliage over flowers. Watch for aphids and powdery mildew. Remove damaged stems as needed; routine deadheading is generally unnecessary for Angelonia.
