What Is the Yellow Trumpet Flower Plant?
The yellow trumpet flower plant, scientifically known as *Tecoma stans* (also called yellow bells or yellow elder), is a member of the Bignoniaceae family. It’s a flowering shrub or small tree that can reach heights of 6 to 12 feet, depending on growing conditions. Its most striking feature is the clusters of bright yellow, trumpet-shaped flowers that bloom from late spring through fall.
These flowers are not just beautiful—they’re also functional. Their tubular shape makes them perfect for attracting pollinators like hummingbirds, bees, and butterflies. The plant’s dark green, glossy leaves provide a lush backdrop, and its overall growth habit is upright and slightly spreading, making it ideal for hedges, borders, or standalone focal points.
Common Varieties
While *Tecoma stans* is the most common species, there are a few popular cultivars worth noting:
- ‘Gold Star’: A compact variety that grows to about 4–6 feet, perfect for smaller gardens or containers.
- ‘Apricot’: Features softer, apricot-yellow blooms and a more delicate appearance.
- ‘Orange Jubilee’: Though not yellow, it’s a close relative with vibrant orange flowers and similar care needs.
These varieties offer flexibility depending on your space and color preferences, but all share the same low-maintenance charm.
Ideal Growing Conditions
To get the most out of your yellow trumpet flower plant, it’s important to mimic its natural habitat. This means plenty of sun, warm temperatures, and well-drained soil.
Sunlight Requirements
This plant is a true sun worshipper. It needs a minimum of 6 to 8 hours of direct sunlight each day. In fact, the more sun it gets, the more flowers it will produce. If you’re growing it in a partially shaded area, you may notice fewer blooms and leggier growth. For best results, plant it in a south- or west-facing spot where it can soak up the rays.
Soil and Drainage
While the yellow trumpet flower isn’t overly picky about soil type, it does require good drainage. Heavy clay soils can lead to waterlogged roots and root rot, especially in cooler months. Aim for loamy or sandy soil with a pH between 6.0 and 7.0. If your soil is heavy, consider amending it with compost or planting in raised beds to improve drainage.
Climate and Hardiness
This plant thrives in USDA hardiness zones 9–11, where it can grow year-round as a perennial. In zones 7 and 8, it may survive mild winters but could die back and regrow in spring. In colder regions (zones 6 and below), it’s best grown as an annual or in containers that can be brought indoors during winter.
Temperatures below 25°F (-4°C) can damage or kill the plant, so if you live in a cooler area, consider growing it in a pot so you can move it to a protected space when frost threatens.
Planting and Transplanting Tips
Whether you’re starting from seed, a cutting, or a nursery plant, proper planting techniques set the stage for success.
Starting from Seed
Seeds can be started indoors 6–8 weeks before the last frost. Soak them in warm water for 24 hours to speed up germination, then plant them in seed-starting mix about ¼ inch deep. Keep the soil moist and warm (70–75°F), and seedlings should appear in 2–3 weeks. Transplant outdoors only after all danger of frost has passed and nighttime temperatures stay above 50°F.
Transplanting Nursery Plants
When transplanting a young plant from a container, dig a hole twice as wide and just as deep as the root ball. Gently loosen the roots before placing the plant in the hole, then backfill with soil and water thoroughly. Space plants 3–5 feet apart if planting multiple shrubs to allow for growth and airflow.
Container Growing
The yellow trumpet flower adapts beautifully to container life. Choose a large pot (at least 12–14 inches in diameter) with drainage holes. Use a high-quality potting mix and place the container in a sunny location. Container-grown plants dry out faster, so check the soil moisture more frequently, especially in hot weather.
Watering and Fertilizing
One of the biggest advantages of the yellow trumpet flower plant is its drought tolerance—but that doesn’t mean you can ignore watering entirely.
Watering Schedule
During the first growing season, water your plant deeply once or twice a week to help establish a strong root system. After that, it can handle dry spells much better. In general, water only when the top 2–3 inches of soil feel dry. Overwatering is a common mistake—yellowing leaves or leaf drop can be signs of too much moisture.
Fertilizing for Better Blooms
While not a heavy feeder, the yellow trumpet flower benefits from occasional feeding. Apply a balanced, slow-release fertilizer (like a 10-10-10) in early spring and again in midsummer. Alternatively, use a liquid fertilizer every 4–6 weeks during the growing season. Avoid over-fertilizing, as this can lead to lush foliage at the expense of flowers.
Organic options like compost or worm castings are also excellent choices. A 1–2 inch layer of compost around the base of the plant in spring provides nutrients and helps retain moisture.
Pruning and Maintenance
Regular pruning keeps your yellow trumpet flower looking tidy and encourages more blooms.
When to Prune
The best time to prune is in late winter or early spring, just before new growth begins. This allows you to shape the plant and remove any dead or damaged branches from winter.
How to Prune
Use clean, sharp pruning shears to cut back up to one-third of the plant’s height. Focus on removing crossing branches, thinning out dense areas, and cutting back leggy stems. This promotes airflow and sunlight penetration, reducing the risk of disease.
After heavy flowering in summer, you can also do light pruning to remove spent blooms and encourage a second flush of flowers.
Winter Care
In warmer zones, the plant may need little winter care beyond occasional watering during dry spells. In cooler areas, protect container plants by moving them indoors or to a garage. For in-ground plants, apply a layer of mulch around the base to insulate the roots.
Pests and Diseases
The yellow trumpet flower is generally pest-resistant, but a few issues can arise under certain conditions.
Common Pests
Aphids and spider mites may appear during hot, dry weather. These can usually be controlled with a strong spray of water or insecticidal soap. Regularly inspecting the undersides of leaves helps catch infestations early.
Disease Prevention
Root rot is the most common disease, caused by poor drainage or overwatering. To prevent it, ensure your soil drains well and avoid letting the plant sit in water. Fungal leaf spots can also occur in humid conditions—improve airflow and avoid wetting the foliage when watering.
Deer and Rabbit Resistance
Good news for gardeners in rural areas: the yellow trumpet flower is rarely bothered by deer or rabbits. Its slightly bitter taste and tough leaves make it unappealing to most wildlife.
Companion Planting and Landscaping Uses
This versatile plant fits beautifully into many garden designs.
Companion Plants
Pair it with other sun-loving, drought-tolerant plants like lantana, salvia, or lavender. These companions share similar care needs and create a vibrant, low-maintenance border.
Landscaping Ideas
- Use as a backdrop in perennial beds.
- Plant along fences or walls for a natural screen.
- Create a tropical-themed garden with bird of paradise and hibiscus.
- Feature in large containers on patios or decks.
Its upright form and bright flowers make it a standout in any setting.
Conclusion
The yellow trumpet flower plant is a joyful, easy-care addition to any garden. With its dazzling blooms, wildlife appeal, and resilience, it’s no wonder it’s a favorite among gardeners of all levels. By providing plenty of sun, well-draining soil, and occasional pruning, you’ll enjoy months of golden flowers and happy pollinators.
Whether you’re a beginner or a seasoned green thumb, this plant offers beauty with minimal effort. So go ahead—plant a yellow trumpet flower and let a little sunshine into your garden.

They are fast growers, often adding 2–3 feet per year in ideal conditions. This makes them great for quickly filling garden spaces or creating privacy screens.
Do yellow trumpet flowers come back every year?
In USDA zones 9–11, they return as perennials. In colder zones, they may die back in winter but can regrow from the roots in spring if protected.
Why are my yellow trumpet flowers not blooming?
Common causes include too little sunlight, over-fertilizing (especially with nitrogen), or recent transplant shock. Ensure full sun and balanced feeding for best results.
Can I propagate yellow trumpet flowers from cuttings?
Yes! Take 6-inch stem cuttings in spring or summer, remove lower leaves, dip in rooting hormone, and plant in moist potting mix. Keep warm and humid until roots develop.
