2024: Year of the Angelonia

This “summer snapdragon” thrives in heat and arid locations, making it a perfect choice for most summer gardens.

History and Overview

Angelonia, sometimes referred to as “summer snapdragon,” is a genus of approximately 30 species, which grow natively in regions from Mexico to Argentina. The plants grow mostly upright, with stalks filled with flowers. Angelonia florets resemble tiny orchid-like blooms and their shape aids in pollination through hairs in the inner corolla that help bees forage for pollen. With its tolerance to heat and dry conditions, Angelonia thrives through most summer gardens with little extra maintenance or care.

Angelonia angustifolia is the most recognizable garden Angelonia species. It is native to Mexico and the West Indies. A. angustifolia has upright flowers and a somewhat bushy habit. It is noted for its long summer bloom of snapdragon-like flowers. Plants typically grow 12-18? tall. Stems are narrow with oblong to lanceolate, green leaves. The foliage has a soft scent, and flower colors are a wide range from white, purple, light pink, dark reds, bicolor flowers, and more.

These three species, Angelonia crassifolia, Angelonia integerrima, and Angelonia campestris are more of a sub-shrub genus in terms of habit and look. They are native to Brazil and first classified by botanists in the early 1800s. They grow much more wild primarily in a dry tropical biome.

Angelonia salicariifolia was published in floral journals in 1812 as the result of excursions to Bolivia, Brazil, and northeast Argentina. This genus has herbal and medicinal uses in some species. It also grows primarily in the seasonally dry tropical biome.

Angelonia Growing Tips

Sowing Angelonia Seeds

When sowing, do not cover the seed – Light is required for the germination of Serena or Serenita Angelonia. Seed Angelonia needs about 13-15 weeks from sow to finish. Also, do not pinch when growing Angelonia from seed. Pinching will result in an uneven plant habit and a delay of flowering.

In the garden, Angelonia are very low maintenance

1. No pruning or deadheading required
2. Plants do their best in warmer temperatures
3. Angelonia grows slowly when the temperature is below 64°F (18°C).
4. As a drought-tolerant plant, once established Angelonia will thrive in soil that is not saturated with moisture.

Angelonia: A Versatile Plant for Many Uses

Hanging Baskets

Grow spreading Angelonia in a 10-12 inch (25-30 cm)basket, 3 plants per basket. You can combine a single color or mix colors in the basket. Either way will give a flowerful and colorful hanging basket for the garden.

Combination Container

Angelonia can be a Thriller, a Filler, or a Spiller plant for a combo. Combining different Angelonia habits with other sun-loving plants in a larger container is a good match.

Landscape

Growing Angelonia in-ground for landscaping makes gardening easy. The plants are well-behaved in the garden, not tangling with other plants. Their blooms also last a long time, providing season-long color.
