Angelonia angustifolia Care Guide for Alans Garden

Botanical Name: Angelonia angustifolia
Common Name: Summer Snapdragon, Angelonia
Plant Type: Flowering perennial (often grown as an annual)

Light

• Grows best in full sun with 6–8 hours of direct sunlight daily.
• Can tolerate light partial shade, but flowering will be reduced.
• More sunlight encourages stronger growth and abundant blooms.

Watering

• Water regularly during establishment.
• Once established, Angelonia is fairly drought-tolerant.
• Allow the top layer of soil to dry slightly between waterings.
• Avoid overwatering, as constantly wet soil can lead to root problems.

Soil

• Prefers well-draining, fertile soil.
• Grows well in garden beds, borders, and containers.
• Enrich the soil with compost for healthier growth and longer flowering.

Temperature & Humidity

• Thrives in warm temperatures between 20–35°C.
• Handles heat and humidity exceptionally well.
• Suitable for tropical and subtropical climates.

Fertilizing

• Feed once every 3–4 weeks during the growing season with a balanced liquid fertilizer.
• Excess fertilizer may encourage leafy growth at the expense of flowers.

Pruning & Maintenance

• Remove spent flower spikes to encourage continuous blooming.
• Trim leggy stems lightly to maintain a compact shape.
• Unlike many flowering plants, Angelonia often blooms continuously without frequent deadheading.

Flowering

• Produces spikes of colorful flowers in shades of purple, pink, white, blue, and lavender.
• Blooms continuously from spring through the warm season.
• Flowers attract bees, butterflies, and other pollinators.

Common Problems

• Yellow leaves: Usually caused by overwatering or poor drainage.
• Poor flowering: Often due to insufficient sunlight.
• Pests: Occasionally affected by aphids, whiteflies, or spider mites.
