There are many stunning flowers that look like trumpets, each using that form for a specific purpose. The trumpet shape in flowers is a clever evolutionary design for attracting specific pollinators, and it appears in a surprising variety of garden plants.
These blooms are not just beautiful; they are functional. The long, tubular form acts as a perfect landing pad and nectar guide for creatures like hummingbirds, moths, and bees. This article will show you the most popular and unique trumpet-shaped flowers you can grow.
You will learn how to identify them, care for them, and use them in your landscape. Whether you have a sunny border or a shady corner, there’s a trumpet flower for you.
Flowers That Look Like Trumpets
The world of trumpet-shaped flowers is incredibly diverse. They belong to many different plant families and come from various climates. What unites them is that distinctive floral structure.
This shape, known scientifically as a salverform or hypocrateriform corolla, features a long, narrow tube that flares open at the end into a bell or funnel. It’s a design that has evolved independently in many species because it works so well.
Here is a list of some of the most common and beloved garden plants known for their trumpet-like blooms.
- Angel’s Trumpet (Brugmansia)
- Datura (Moonflower)
- Morning Glory (Ipomoea)
- Petunia
- Trumpet Vine (Campsis)
- Honeysuckle (Lonicera)
- Foxglove (Digitalis)
- Lily (Lilium, especially trumpet lilies)
- Narcissus (Daffodil)
- Calibrachoa (Million Bells)
Angel’s Trumpet: The Dramatic Centerpiece
Angel’s Trumpet, or Brugmansia, is perhaps the most iconic plant in this catagory. Its huge, pendulous flowers can reach over a foot in length and fill the evening air with a powerful, sweet fragrance.
These are woody shrubs or small trees that thrive in warm climates. In cooler areas, they can be grown in pots and brought indoors for winter. Their dramatic appearance makes them a fantastic focal point.
Growing and Caring for Angel’s Trumpet
Angel’s Trumpet needs specific conditions to thrive. It is a heavy feeder and drinker during the active growing season.
- Sunlight: Full sun to partial afternoon shade.
- Soil: Rich, well-draining soil. Amend with compost.
- Water: Keep soil consistently moist, not soggy.
- Feeding: Use a balanced, water-soluble fertilizer every two weeks in spring and summer.
- Caution: All parts of the Angel’s Trumpet plant are highly toxic if ingested. Handle with care, especially around children and pets.
Morning Glory: The Classic Climber
Morning Glory vines are famous for their rapid growth and cheerful, funnel-shaped flowers that open with the morning sun. They come in shades of blue, purple, pink, and white, often with a star-shaped pattern inside.
These annuals are easy to grow from seed and will quickly cover a trellis, fence, or arbor. They provide excellent summer color and can even be used as a temporary screen.
How to Start Morning Glory From Seed
Morning Glory seeds have a hard coat. To improve germination rates, a simple pretreatment is helpful.
- Soak the seeds in warm water for 12-24 hours before planting.
- Plant the seeds about 1/4 inch deep in well-draining soil after the last frost.
- Choose a site with full sun for the best flower production.
- Water regularly until the vines are established.
- Provide a sturdy trellis or support for the vines to climb.
Trumpet Vine: A Hummingbird Magnet
Trumpet Vine, also called Campsis or Trumpet Creeper, is a vigorous, deciduous perennial vine. It produces clusters of brilliant orange or red trumpet flowers that are irresistible to hummingbirds.
This plant is incredibly tough and can become invasive if not managed. It’s best planted where it has plenty of room to spread, such as on a sturdy pergola or along a fence line away from your house’s siding.
Controlling Trumpet Vine Growth
Trumpet Vine’s enthusiasm needs to be channeled. With proper management, you can enjoy its beauty without it taking over your garden.
- Plant it in a large, bottomless container sunk into the ground to restrict root spread.
- Prune aggressively in late winter or early spring before new growth begins.
- Remove suckers (new shoots from the roots) as soon as you see them.
- Never let it climb trees or wooden structures you want to preserve, as its aerial roots can cause damage.
Daffodils And Lilies: Spring And Summer Trumpets
The trumpet shape is not just for vines and shrubs. Many beloved bulbs produce classic trumpet blooms. Daffodils (Narcissus) are the heralds of spring, with their central corona forming a perfect trumpet.
True trumpet lilies, a division within the Lilium genus, produce large, outward-facing flowers with long, elegant tubes. They bloom in mid-summer and often have an intense, wonderful fragrance.
Planting Bulbs for Successive Bloom
You can plan your garden to have trumpet flowers from early spring to fall by selecting the right bulbs.
- Plant daffodil bulbs in the fall, about 6-8 inches deep.
- Choose a mix of early, mid, and late-season daffodil varieties for a longer display.
- Plant lily bulbs in the fall or early spring, about 4-6 inches deep.
- Both prefer well-draining soil and a location with at least six hours of sun.
Petunias And Calibrachoa: Container Superstars
For instant color in pots and hanging baskets, few plants beat petunias and their cousin, Calibrachoa (Million Bells). Their prolific, trumpet-shaped flowers come in almost every color imaginable and bloom non-stop from spring until frost with minimal care.
While petunias have larger flowers, Calibrachoa produces hundreds of smaller, petunia-like blooms and is more tolerant of wet weather. Both are excellent choices for beginners.
Keeping Petunias Flowering All Season
A little regular maintenance is the key to preventing these annuals from becoming leggy and stopping bloom.
- Deadheading: Regularly pinch off spent flowers to encourage new buds.
- Pruning: If plants get long and straggly, don’t be afraid to cut them back by one-third to one-half. They will quickly regrow.
- Fertilizer: Feed every two weeks with a water-soluble fertilizer high in phosphorus (the middle number on the label).
- Water: Water container plants thoroughly when the top inch of soil feels dry.
The Pollinator Connection
Why do so many flowers evolve to look like trumpets? The answer lies in co-evolution with pollinators. The shape acts as a specialized tool to ensure successful pollination.
Long-tongued insects like certain moths and butterflies, as well as hummingbirds, are the primary visitors. The tube protects the nectar from “cheater” insects with short tongues, reserving it for the intended pollinators who will reliably transfer pollen.
Attracting Hummingbirds to Your Garden
If you want to see more hummingbirds, planting red, orange, or pink trumpet flowers is the best strategy. Here’s how to create a hummingbird-friendly space.
- Plant clusters of trumpet-shaped flowers to provide a good nectar source.
- Include plants with different bloom times to provide food from spring to fall.
- Provide a shallow water source, like a mister or a birdbath with stones for perching.
- Avoid using pesticides on or near these plants, as they can harm the birds and the insects they also eat.
Designing With Trumpet-Shaped Flowers
These flowers offer more than just individual beauty; they are versatile elements in garden design. Their forms can create rhythm, draw the eye, and establish a mood.
Use tall, dramatic Angel’s Trumpet as a thriller in a large container. Let morning glory vines create a living curtain. Plant a row of trumpet lilies in the back of a border for summer fragrance and height.
Creating a Vertical Garden With Vines
Trumpet vines and morning glories are perfect for adding the vertical dimension to your garden, which maximizes space and adds intrest.
- Structures: Use obelisks, trellises, arbors, or even a simple wire grid attached to a wall.
- Layering: Plant a fast-growing annual vine like morning glory with a slower perennial vine like clematis for sequential bloom.
- Color Themes: Choose vine flower colors that complement your house siding or other garden structures.
- Ensure all supports are sturdy and securely anchored, especially for heavy vines like Trumpet Creeper.
Common Challenges And Solutions
Growing trumpet flowers is generally straightforward, but you may encounter a few issues. Most are easily resolved with correct identification and timely action.
Pests like aphids can cluster on new growth, while fungal diseases like powdery mildew can appear in humid, crowded conditions. Understanding the needs of each specific plant is the first step to prevention.
Preventing and Treating Powdery Mildew
This white, powdery fungus appears on leaves and stems, especially in late summer. It’s common on plants like phlox and lilacs, but can affect others.
- Choose resistant varieties when available.
- Plant in areas with good air circulation and avoid crowding plants.
- Water at the soil level, not overhead, to keep foliage dry.
- If mildew appears, treat early with a fungicidal soap or a homemade spray of 1 tablespoon baking soda, 1/2 teaspoon liquid soap, and 1 gallon of water.
Frequently Asked Questions
Here are answers to some common questions about trumpet-shaped flowers.
Are all trumpet-shaped flowers fragrant?
No, not all of them are. Fragrance is another pollinator attractant that evolved in some species but not others. For example, Angel’s Trumpet and many lilies are very fragrant, especially in the evening to attract moths. Morning glories and trumpet vines have little to no scent but rely on bright color to attract hummingbirds.
What is the difference between Brugmansia and Datura?
This is a common point of confusion. Both are called “trumpet” flowers and are toxic. Brugmansia (Angel’s Trumpet) is a woody shrub with large, pendulous flowers that point downward. Datura (often called Moonflower or Jimsonweed) is usually an herbaceous annual or short-lived perennial with flowers that point upward. Their seed pods are also different; Datura has a spiny pod.
Can I grow trumpet flowers in shade?
Most trumpet-shaped flowers, especially those that attract hummingbirds, require full sun to bloom their best. However, some, like Foxglove (Digitalis) and certain types of Honeysuckle, can tolerate partial shade. Always check the specific light requirements for the plant you choose.
How do I get my trumpet vine to bloom?
If your trumpet vine is all leaves and no flowers, it’s usually due to too much nitrogen fertilizer (which promotes leafy growth), too much shade, or the plant being too young. Ensure it gets at least six hours of direct sun, avoid high-nitrogen fertilizers, and use a fertilizer higher in phosphorus to promote blooming. Sometimes, a little stress, like slightly dry conditions, can also trigger flowering.
Are there any blue trumpet-shaped flowers?
Yes, several. The classic morning glory comes in beautiful sky blue and deep blue shades. Clitoria ternatea (Butterfly Pea) is a vine with striking, vivid blue flowers. Some varieties of Petunia and Browallia also offer blue, trumpet-like blooms. The color blue is particularly attractive to bees.
