Angelonia, also known as summer snapdragon, presents a charming appearance with its slender, lance-shaped leaves arranged neatly along upright stems. Rising above the foliage, tall spikes bear clusters of small, delicate flowers resembling snapdragons, coming in deep purple.


The most attention-grabbing flowers tend to be the big and showy types like zinnias, dahlias, roses, and daisies, but I’m here to talk about one of the easiest-to-care-for spike flowers there is.

You may have seen this flower planted en masse on a slope or in containers on a back patio and thought it was a snapdragon or a new cultivar of foxglove. It’s a fairly young genus called Angelonia, and it’s here to stay! 

Growers love the bold colors, ease of care, and drought resistance of angelonia. Warm climate growers love it for its high yields and great performance throughout the season, even when temperatures skyrocket. 

Let’s talk about how easy it is to plant, grow, and care for angelonia

What Is It?

Close-up of blooming Angelonia in the garden. Angelonia plants showcase lush green foliage characterized by lance-shaped leaves, forming a verdant backdrop for its abundant clusters of delicate, snapdragon-like flowers. These flowers which come in a variety of colors including pink and lavender, adorn sturdy spikes rising gracefully above the foliage.
Opt for Angelonia as a resilient summer filler with lovely scents.

Angelonia is a bushy, spiky, heat-loving annual that serves as a fill-in for snapdragons during the peak of summer and in the fall when snapdragons have dwindled. It also adds height to your garden design.

They look delicate, but they’re hardy, heat-tolerant, and resilient. Their shades of blues, pinks, and violets complement cottage gardens, perform well along borders and in containers, and are overall low-maintenance. 

The Angelonia genus was identified in the late 1990s and consists of about 30 species. Florists and backyard gardeners adore these flowers for their sweet apple, grape, or vanilla scent and long vase life. 

Native Area

In a flower bed, colorful Angelonia flowers create a striking display with their vibrant hues, ranging from soft pastels to rich jewel tones. Rising on sturdy stems amidst lush green foliage, these snapdragon-like blossoms form dense clusters.
Native to Mexico and the West Indies, it thrives in subtropical climates.

Angelonia is native to Mexico and the West Indies, thriving in high heat.

Angelonia pink flowers boast an enchanting delicacy, with each blossom featuring five distinct petals that resemble those of a snapdragon, arranged symmetrically around a slender, tubular throat. These blooms emerge atop tall spikes, towering above the lush, lance-shaped green leaves.
Angelonia varieties grow erect, boasting colorful blooms and sweet fragrance.

Similar to true snapdragons, most varieties of angelonia grow erect while others grow more horizontally yet not trailing. The tall varieties may rise to 36″ or taller, while shorter varieties stay under one foot in height. They all boast shades of blue, purple, pink, white, and, more recently, reds. 

These flowers are nicknamed “summer snapdragons,” but they don’t have a hinge on their blooms like true snapdragons do. Instead, their ¾ inch flowers are fused, tubular, and two-lipped. The foliage is dark green and glossy. Tiny hairs on the leaves and stems give it a sticky feeling. The blooms offer a sweet fragrance that is more intense and lingers in the air during periods of heat. 

How to Grow

Angelonia is praised for its easy maintenance and cheerful, bold-colored spikes that attract pollinators.

They present a captivating sight with their ethereal beauty, boasting delicate petals in shades ranging from pale lavender to deep violet. These blossoms adorn sturdy spikes that rise elegantly above the lush green foliage, which consists of lance-shaped leaves arranged symmetrically along the stems.
Plant in sunny areas for optimal flowering.

Place angelonia in areas that receive full sun for the best flowering performance, although some varieties will tolerate partial shade.

Angelonia goyazensis Benth is distinguished by its compact stature and vibrant foliage, with lance-shaped leaves showing a glossy green hue. Rising above the foliage are tall, slender spikes adorned with clusters of delicate, snapdragon-like flowers of rich violet color.
Make sure the soil dries out between waterings.

Water regularly and deeply as the plants get established. Mature plants can tolerate drought conditions. In times of extreme dryness, water with drip irrigation, but allow the soil to dry out before watering sessions.

Angelonia plants exhibit a compact yet graceful appearance, adorned with glossy green lance-shaped leaves that form a lush backdrop for their abundant flowers. They grow spaced apart in clumps. Rising above the foliage are tall spikes bearing clusters of delicate snapdragon-like blooms in a variety of colors, including shades of pink and lavender.
For optimal growth, use moist and well-draining soil.

Soil preference is moist and well-draining. angelonia does not tolerate clay-like or compacted soil that does not allow roots to breathe. Add a thick layer of compost to your garden bed before transplanting to help with drainage. Ensure the area is weed-free. The pH should be slightly acidic at 5.5 to 6.2.

If your garden doesn’t have well-draining, fertile soil, plant in fabric grow bags or pots! These unique flowers perform very well in containers. Just remember to provide extra supplemental water because they can’t reach down into the earth to find it when the potting soil dries out.

Temperature and Humidity

The flowers, reminiscent of snapdragons, bloom in clusters along tall, sturdy spikes, showing a range of colors including white, pink, lavender, and purple.
This plant thrives in heat and drought, but needs airflow to prevent fungus.

Once established, angelonia can withstand extreme heat and drought and doesn’t seem to mind humidity. However, proper airflow reduces the risk of fungal disease, which tends to increase during extended periods of humidity. 

Growth slows when temperatures are below 65°F (18°C), making this the perfect garden addition for southern growers that experience high humidity and prolonged periods of heat.

Angelonia salicariifolia, commonly known as willowleaf angelonia, presents a graceful appearance with its slender, willow-like leaves that cascade elegantly along slender stems. Rising above the foliage are tall spikes adorned with clusters of small, snapdragon-like flowers in shades of pink and white.
Fertilize lightly with 10-5-10 formula to maintain proper growth.

Apply fertilizer regularly but lightly so stems stay bulky and at the proper height. Use a 10-5-10 slow-release formula monthly or bi-monthly, following the instructions on the packaging.

Too much fertilizer can cause legginess and more foliage than flowers. Slow-release fertilizer is ideal to prevent fertilizer burn or excessive foliage growth. Diluted liquid fertilizers are a close second option.

Low-maintenance summer snaps thrive in containers and in the ground.

Is your landscape in need of an easygoing thriller? Add angelonia anywhere that needs bright colors and a little height. No staking is necessary. 

Summer snaps are low-maintenance, needing very little attention, supplemental water, or pruning. While they can be grown in containers or hanging baskets, they perform best in the ground without extra attention

These flowers come in a variety of colors, including shades of white, pink, and purple.
Regular harvesting ensures season-long blooming.

Summer snaps will bloom for you all season with regular harvesting. If you pinch as you would with traditional snapdragons, it may lead to delayed flowering but will encourage a more compact and bushy plant.

Deadhead spent blooms. Cut back stems in mid-summer and optionally fertilize to refresh and rejuvenate your patch of summer snaps.

These blooms attract pollinators.

Angelonia blooms from late spring to the first frost, depending on your growing zone and when your seeds are sown. Its sweet smell and open, easy-to-access florets attract beneficial pollinators, butterflies, and hummingbirds

Planting and Propagation 

You can propagate this flower by seed, stem cuttings, and root mass division. Plant angelonia after the risk of frost has passed in your area.

Start seeds indoors with warmth and light.

Angelonia seeds are very tiny and borne in seed pods. They can’t germinate until they’re released naturally or removed by human intervention. Seed companies take care of seed pod removal and often pelletize the seeds for ease of sowing.

Sow seeds indoors six to eight weeks before your last frost date. Use a heat mat set to 70-75°F (21-24°C) and a strip tray filled with high-quality seed-starting mix. Gently press seeds into the mix but do not cover as light aids in germination—bottom water to keep the seeds from becoming displaced.

Germination should occur in 10-14 days after sowing. Provide direct sunlight or artificial lighting right away to avoid leggy seedlings. Step up into larger pots when they have a healthy root system and stem. 

Allow seedlings to grow indoors with ample heat, water, and sunlight until they have several sets of true leaves. Harden them off properly before transplanting them outdoors after the risk of frost has passed. 

Note that seeds saved from your garden will not produce an exact clone of the mother plant unless they are from the ‘Serena’ series.

Stem Cuttings

Propagate non-patented plants by cuttings.

Perform this method with non-patented plants. Locate healthy plants at the beginning of the season. Using sharp, clean shears, cut about a four-inch cutting below a node on the stem near the base of the plant. Optionally, dip the end in rooting hormone powder, then add it to a container of potting mix.

Cover the surface with vermiculite to help with drainage. Remove any flowers and buried lower leaves. This will encourage the plant to send energy into creating new roots rather than on the blooms. 

Roots will form within two to four weeks. Step up as needed and transplant once the seedlings are properly hardened off. 

Pro tip: Alternatively, add the cutting to a jar of fresh water and place it in a sunny window or outside in its natural environment. Change the water often.

Root Mass Division

Divide summer snaps for perennial growth.

This is an uncommon method, but it can be done in areas where summer snaps survive as a perennial. Dig up an established plant in the spring and carefully separate its root system into smaller sections.

Ensure each section has ample and healthy roots. Transplant the sections into fresh potting soil and treat as you would a young seedling or plant.

Rising above this verdant backdrop are tall, erect spikes adorned with clusters of small, tubular flowers resembling snapdragons. These blooms are a rich purple color.
Plant your plants in the morning, giving them space and regular watering to settle in happily.

Transplant your purchased plants, seedlings, or hardened-off cuttings in the morning on a cloudy or semi-cloudy day once the risk of frost has passed. Loosen the soil and dig a hole just slightly larger than the root ball. Place the seedling in the hole and surround it with native soil, tamping it down slightly so the roots have good soil contact. 

Space plants at 9-18 inches. Water using drip irrigation at least once a week to help the plants establish. 

‘Serena®’ and its compact counterpart, ‘Serenita®,’ are the only seeds available on the market today. An exact clone of the parent plant is guaranteed and can be done safely by home gardeners.

Other series and cultivars of angelonia are available in plug form. This means they have been vegetatively or asexually propagated. They should only be propagated by cuttings or root mass division to ensure the same floral display.

Common Problems

Prevent root rot with well-draining soil.

Angelonia has very few problems under ideal conditions and when properly maintained. If you notice aphids in your angelonia patch, they can be sprayed off with a gentle but solid water stream. Neem oil and insecticidal soap are alternatives. Follow the instructions on the packaging. 

Spider mites may feed on foliage, leaving behind pale spots, making your flower patch unmarketable and unattractive. The mites’ presence is obvious by the webbing they leave in their wake. Otherwise, they’re very tiny and hard to spot. If you have cobweb-looking structures in your angelonia patch, treat them with neem oil or insecticidal soap. Wipe down your plants with a damp cloth in between these treatments.

Powdery mildew is a concern if there is not ample airflow where humidity levels remain high. Cultivars range from low to high resistance to root, crown, and stem rot. 

Root rot is caused by soggy water and roots that can’t breathe. Fungi, bacteria, and several molds that develop in the soil cause this disease. Prevent root rot by ensuring your soil is properly draining. Pay close attention to above-ground symptoms like slow or stunted growth, yellow patches, wilting, and leaf drop. If you notice yellowing leaves, cut back on watering. 

Angelonia is deer and rabbit-resistant. 

Frequently Asked Questions

How should summer snapdragons be designed in the garden? 

Angelonia adds height and whimsical beauty to any style garden, planted en masse as a statement, along fences and borders, or on slopes to prevent erosion. Cascading varieties perform well in hanging baskets, along retaining walls, and in window boxes. If you grow snapdragons, mix in some summer snaps that will fill the bloom gap during peak summer heat when snapdragons slow down.

What are some good companion plants?

Grow Angelonia alongside ornamental grasses, geraniums, coneflower, sweet alyssum, or dusty miller for a cool contrast. Showcase tall varieties as the centerpiece of a large container or standalone garden, surrounded by native grasses, flowering ground cover, and small shrubs.

Is angelonia a perennial or annual? 

Angelonia survives as a perennial in zones 9-11 and is most often grown as an annual in cooler regions. Container-grown plants don’t typically survive winters when they’re brought indoors so your best bet is to save seeds or buy new plants each year.

Final Thoughts

If you’re a southern grower or experience high humidity levels, summer snaps are a great option for your garden. Enjoy them as perennials in zones 9-11 and a long-time blooming annual in northern climates. Use them as a filler, thriller, or spiller.
