Angelonia annual or perennial

Landscape professionals and horticulturists are raving about Angelonia’s heat and drought tolerance, extended bloom period and performance in the landscape. Better Homes and Gardens magazine listed it as one of the top 20 annuals of 2008 and it was a Georgia Gold Medal Winner in 2009.

Angelonia is an erect little perennial (in zones 8 – 11) with smooth stems and narrow 2-3 inch leaves with toothed margins and pointed tips. Some people say the foliage smells like apples. The flowers are rose lilac to violet to blue, almost an inch across and borne in slender upright spikes to 8 inches long. The flowers bloom over a long period in summer – 4-6 weeks in temperate climates and even longer in zones 8-11 — the blooming season is May to October in North Texas. Angelonia is evergreen with soft (not woody) stems and a bushy habit, and gets 12-18 inches tall with a spread of about 12 inches.

‘Angelmist’ Angelonia is a vegetatively propagated offering from Ball Horticultural Company and is considered hardy in Zones 8 – 11. The ‘Serena’ Series cultivars are new introductions that are particularly noteworthy because they may be grown from seed — Serena Series plants are slightly more compact than species plants, typically growing to 10-14 inches tall. Serena flowers have an impressive spring to early fall bloom period. Angelface® Blue is an offering from Proven Winners. It comes in six different colors and is extremely vigorous and showy, and gets about 2 feet tall. It is considered an annual except in zones 8 – 11 — San Antonio is Zone 8b and it is usually root-hardy (top freezes down but it sprouts again from root system the following spring).

Angelonia is native to Mexico and the West Indies.

Culture – A slow-release fertilizer, such as Osmocote, incorporated into soil at planting time will ensure uniform growth. Supplement the granular fertilizer with liquid feed, as needed, to keep plants looking their best. Let the plants dry out between waterings but be prepared to provide supplemental irrigation during dry spells.

Light: Full sun but will tolerate light shade.

Moisture: Angelonia should have regular watering for best performance, but established plantings are moderately drought tolerant. Allow the soil to dry out between waterings.

Hardiness: USDA Zones 8 – 11. Angelonia is a perennial in zones 8-11 — in Zone 8 it is usually root-hardy (top freezes down but it sprouts again from root system the following spring). Elsewhere it is grown as an annual or in a container to be brought indoors in cold weather.
The foliage and flowers are hardy to 30 degrees F.

Propagation: Propagate Angelonia from tip cuttings, by division of the root mass, or by seed. For a head start, sow seed indoors at 70-75 degrees F., 6-8 weeks before the last expected frost. Of course, the patented cultivars should not be commercially propagated without a propagation license from the patent holder but home gardeners can experiment with a seedling population.

Usage: With their short stature and long lasting colorful blooms, Angelonias are perfect as summer bedding plants. For a massed effect, space plants 9-12 inches apart. They also make great container plants for porch planters and window boxes. In zones 9-11 use as flowering edging in front of perennial beds and borders. They’re good for cut flowers too.

Maintenance: Blooms all season; heat and drought tolerant plants; scented foliage; low maintenance (Deadheading Is Not Necessary) but periodic cut-back is HIGHLY recommended – the plant will be twice as thick a week later if you can bring yourself to cut to the ground some or all of the tallest upright stems covered with snapdragon-like flowers. In a few days the plant will look every bit as bushy as before!

Angelonia is drought-tolerant and somewhat wet-tolerant as well but always remember: Even drought tolerant annual and perennial plants will need water for several weeks while they get established. After this, little or no supplemental water will be necessary when planted in the ground except in the complete absence of rainfall. No plant is truly drought tolerant in a container; regular watering is necessary for all plants in containers.

AND I HAVE SAVED THE BEST FOR LAST—Angelonia is DEER RESISTANT. Angelonia is listed as a deer resistant annual on many lists. However, we don’t believe it UNLESS we have done it in Texas. For several years, Forrest Appleton has tested this plant and found it to be truly deer-resistant. Images are attached showing Ruellia graecizans being eaten next to a 3-year-old ‘Serena’ Angelonia with no damage in July. But (and there is always a but) when planting ALL supposedly deer-resistant plants in areas where deer are active some defensive measures are called for at the time of planting. Deer are very curious creatures and are “duty bound” to taste test any new offerings. If you cannot (or prefer to not) physically exclude the deer by a method such as fencing, you should use one of the repellants that are on the market until the deer get used to the plant being in their forage area. This may take up to 6 months. A product called Liquid Fence has worked for us.

Care Of Angelonia: How To Grow An Angelonia Plant

Angelonia (Angelonia angustifolia) gives the appearance of being a delicate, finicky plant, but growing Angelonia is actually quite easy. The plants are called summer snapdragons because they produce a profusion of flowers that resemble small snapdragons all summer, and in warm climates the flowering continues into fall. Let’s learn more about growing Angelonia in the garden.

About Angelonia Flowers

An Angelonia plant grows about 18 inches tall, and some people think the fragrant foliage smells like apples. The flowers bloom on upright spikes at the tips of the main stems. Species flowers are bluish-purple and cultivars are available in white, blue, light pink and bicolors. Angelonia flowers don’t need deadheading to produce a continuous display of blossoms.

Use Angelonia as an annual bedding plant in borders or plant them in masses where they make a striking display. They also grow well in pots and window boxes. They make good cut flowers, and the foliage retains its fragrance indoors. In USDA plant hardiness zones 9 through 11, you can grow them as perennials.

Care of Angelonia

Choose a site in full sun or light shade and set out bedding plants in spring two or three weeks after the last expected frost. Space them 12 inches apart in cool climates and 18 to 24 inches apart in warm regions. When the young plants are 6 inches tall, pinch out the tips of the main stems to encourage branching and bushiness.

Seeds for Angelonia plants aren’t readily available, but if you can find them you can sow them directly outdoors in USDA zones 9 through 11. Start them indoors in cooler zones. Seeds usually take about 20 days to germinate, but they can take up to two months.

Angelonia plants prefer moist, well-drained soil but they can withstand brief dry spells, especially if the soil is enriched with compost before planting. Keep the soil around young seedlings moist. Allow the soil to dry out between waterings once the plants are well-established.

Give the plants a light feeding with 10-5-10 fertilizer once a month, but don’t overdo it. If you give them too much fertilizer, they will produce more foliage and fewer flowers. Feed plants in containers with liquid fertilizer mixed according to the package instructions.

If Angelonia plants begin to sprawl in midsummer, cut them back by about half their height. They will soon regrow and produce a fresh flush of flowers.

Ornamental Features

AngelMist® Spreading Blue Angelonia has masses of beautiful spikes of powder blue pea-like flowers rising above the foliage from late spring to late summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its small fragrant narrow leaves remain green in color throughout the year. The fruit is not ornamentally significant.

Landscape Attributes

AngelMist® Spreading Blue Angelonia is an herbaceous annual with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This plant will require occasional maintenance and upkeep, and should not require much pruning, except when necessary, such as to remove dieback. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

AngelMist® Spreading Blue Angelonia is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use
  • Container Planting
  • Hanging Baskets

Planting & Growing

AngelMist® Spreading Blue Angelonia will grow to be about 20 inches tall at maturity, with a spread of 20 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Although it’s not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

AngelMist® Spreading Blue Angelonia is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. With its upright habit of growth, it is best suited for use as a ‘thriller’ in the ‘spiller-thriller-filler’ container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.

SUMMER SNAPDRAGON

Native to the tropics of the Americas, angelonia is perennial in the Coastal and Tropical South but grown as an annual in most other places. It looks a bit like a shorter delphinium, but it blooms all summer and loves the heat. Showy spikes of blue, purple, pink, or white blossoms appear atop plants that grow 11 feet tall and about 1 feet wide. Periodic deadheading keeps the flowers coming. Excellent both as bedding plants and in containers; provides long-lasting cut flowers. Easy to grow in moist, well-drained soil; not bothered by pests. Deer don’t usually eat it.

Many hybrids are offered. The AngelMist series (1424 inches tall) features a variety of colors, including plum, lavender, and white; some flowers are marked with white, pink, or purple. In the Carita series (1824 inches tall), stems branch at the base, giving the plant a full look. Blossoms are deep pink, lavender, purple, or white. Carita Purple is a particularly good performer. The Serena series (1620 inches tall) is compact, and ‘Serena Purple’ is among the best for the Southern garden. The Serenita series is similar, but shorterplants grow 610 inches tall. The Alonia series features heavily branched plants to 15 inches tall with large, showy flowers. Low-growing, spreading types are ideal for hanging baskets, containers, or in ground cover situations. From the AngelMist Spreading series (410 inches tall) Spreading White and Spreading Purple are highly recommended.

Angelonia Options

There are a variety of angelonia selections to choose from. Some series boast the largest bloom size, while others offer dwarf plants (perfect for container culture). One of the more recent developments in angelonia breeding are seed-grown varieties. This option helps to lower production cost and offers quality plants at inexpensive prices, as well as a good variety of color options.

One of the most acclaimed series of angelonia is Serena. Serena Purple angelonia keeps gardens looking colorful all summer long. Serena flowers have an extensive blooming season and are dependable and hardy, even in blazing summer temperatures.

Unique Flowers & Blooms

If you look closely at the summer snapdragon flowers, you’ll see how this plant got its nickname: Blooms are reminiscent of the wide-open mouth of a monstrous dragon. But, unlike true snapdragons, angelonia flowers present as one fused petal with no hinges. The vibrant flowers tend to appear in the blue/purple to white spectrum. Recently, a few red varieties have popped up, as well.

Good news: Angelonia seeds produce flowers all summer long, and the flower doesn’t require any deadheading to keep blooms going.

Versatile Growing Habits

Angelonia structure, or habit, is rather versatile. Most plants grow upright with spires of flowers and deep green, glossy foliage. The height range is usually between 1 to 2 feet, which makes these plants a great addition to mixed containers (especially since angelonia won’t outcompete its neighbors).

Besides upright, there are also angelonia plants that grow more horizontally instead of vertically. These varieties generally won’t grow more than 1 foot tall but they spread out nicely to fill a garden. If you’re looking for a cascading trailer, angelonia may not be the best fit. This particular trailing type doesn’t readily spill over the edges of containers or walls; instead it grows straight out. Try growing angelonias in a sunny window box.

Lots of Sunshine Is Key

When planting angelonia, look for sunny spots with lots of airflow. Keep in mind that this plant won’t produce many flowers and is more disease-prone when situated in the shade. And don’t worry about too much sun or heat; angelonia are fairly drought tolerant and have no problem with hot summer days.

Plant Angelonia With:

Dusty miller is a favorite because it looks good with everything. The silvery-white color is a great foil for any type of garden blossom, and the fine-textured foliage creates a beautiful contrast against other shapes of green foliage. Dusty miller has also earned a place in the garden because it’s delightfully easy to grow, withstanding heat and drought like a champion.

Geraniums have been a gardener’s favorite for well over a century. The old-fashioned standard for beds, borders, and containers, geranium is still one of the most popular plants today. Traditional bedding types love hot weather and hold up well to dry conditions; many offer colorful foliage. Regal, also called Martha Washington, geraniums are more delicate-looking and do better in the cool conditions of spring and fall. Though most geraniums are grown as annuals, they are perennials in Zones 10-11. Bring them indoors to overwinter, if you like, then replant outdoors in spring. Or they can bloom indoors all year long if they get enough light.

Nasturtiums are so versatile. They grow easily from seed sown directly in your garden’s poorest soil and bloom all season until frost, plus they are never greedy about food or fertilizer. Nasturtiums are available in either spreading or climbing types. Plant spreading types in large containers to spill over the sides. Plant them alongside wide paths to soften the sides for a romantic look. Use nasturtium to brighten a rock garden or between paving stones. Place them at the edges of beds and borders to fill in between other plants and add soft, flowing color. Train climbing types up trellises or alongside fences. The leaves and flowers are edible; use them as a showy plate garnish or to jazz up salads.

You just can’t overdo sage in the garden. This perennial herb earns its keep with fast-growing ways, beautiful blooms, and a flavor deer find distasteful. Once established, plants shrug off drought, although it’s wise to keep plants well-hydrated through the hottest parts of summer if you want a steady supply of supple foliage. Some gardeners pinch out flower buds to keep leaves forming, but the blooms are beautiful. If you choose to let plants flower, when blossoms fade, cut plants back to beneath where flower buds formed. Don’t cut back to woody stems that have no leaves; those most likely won’t sprout again. Sage plants typically require replacing every 3-4 years, as plants become woody and produce fewer leaves. The uses of sage are wide ranging. Besides its popular use as a culinary herb, sage is also commonly pressed into service in cosmetics, perfumes, and soaps. Some naturalists rub it on their skin as an insect repellent. Hanging dried leaves among woolen clothing deters moths. Burning sage removes unpleasant odors, such as lingering cigarette smoke or cooked fish smells.
