Angelonia Summer Snapdragon

Angelonia Summer Snapdragon (Angelonia angustifolia)

Angelonia brings steady, upright color through the hottest part of the year, when many annuals start to fade. It flowers hard from late spring into fall, giving beds and containers a clean, vertical look that stays neat with minimal effort. This is an easy win for sunny spots where you want strong color without constant watering and trimming. If you garden in heat and humidity, angelonia is one of the most dependable ways to keep the landscape looking fresh.

Distinctive Features

Angelonia produces spikes of small, snapdragon-like flowers in shades of purple, lavender, pink, and white, often with attractive bicolor effects. The plants are upright and bushy with narrow, glossy green leaves and strong branching that keeps the shape full. Blooms keep coming all summer, and many plantings stay attractive without regular deadheading. It is also valued for excellent heat tolerance and good performance in humid climates.

Growing Conditions

• Sun: Full sun for best flowering, with light afternoon shade helpful in extreme heat.
• Soil: Moist, well-drained soil, and it performs well in average to fertile mixes that do not stay soggy.
• Water: Water regularly to establish, then water when the top soil dries, because it has some drought tolerance once rooted in.
• Zones: USDA Zones 9 to 11 as a tender perennial, and grown as an annual in colder zones.
• Mature Size: Typically 12 to 24 inches tall and 12 to 18 inches wide, depending on variety and growing conditions.

Ideal Uses

• Focal Point: Use a tight grouping in a sunny bed or a large pot where the flower spikes create a crisp vertical accent all season.
• Containers: Ideal for hot patios and entry pots where long bloom and clean structure matter.
• Bedding and Borders: Mass for reliable summer color with a tidy, upright habit.
• Pollinator Plantings: Supports bees and butterflies while keeping the planting looking polished.
• Heat-Tough Color Blocks: Works well in full-sun areas that bake, including along driveways and reflective walls.

Low Maintenance Care

• Deadheading: Optional, because many plantings keep blooming well without it, but trimming spent spikes can tidy the look.
• Pinching: Pinch young plants once to encourage branching and a fuller, bushier shape.
• Watering: Avoid constantly wet soil, and water deeply rather than lightly and often.
• Feeding: Feed lightly during the growing season if grown in containers to support continuous flowering.
• Cleanup: Shear lightly in midsummer if needed to refresh growth and encourage a new flush of blooms.
