Pyrostegia venusta or the Orange Trumpet Vine is a must have plant for anyone looking for vivid flowers! Here’s everything about growing it.
Commonly known as the Flamevine or Orange Trumpet Vine, Pyrostegia venusta is a vigorous climber that can be a fantastic addition to any wall or space.
Pyrostegia Venusta Information
This fast-growing evergreen vine can reach impressive lengths, often climbing up to 20-40 feet or more. Flamevine has long, slender stems with tendrils that aid in climbing and attaching to structures or other plants.
Pyrostegia venusta produces dense clusters of vibrant orange to reddish-orange trumpet-shaped flowers, its most striking feature. Orange Trumpet Vine is renowned for its spectacular and abundant blooming. It typically flowers during the winter, from late fall to early spring, although the exact timing may vary depending on the region and climate.
The trumpet-shaped flowers of Pyrostegia venusta are around 5 centimeters long and have a flared, five-lobed shape. They are rich in nectar, attracting pollinators, including hummingbirds, butterflies, and bees. The flowers’ vivid orange color gives the plant its common name, “flame vine.” Flamevine‘s foliage consists of leathery, dark green leaves that are elongated and lance-shaped, with a glossy appearance.
Pyrostegia venusta is known for its vigorous growth habit. It climbs using twining tendrils and quickly covers walls, fences, trellises, or other supporting structures. Flamevine can also scramble over the ground if not trained or pruned.

How to Grow Pyrostegia Venusta?
Growing Pyrostegia venusta from seeds can be an exciting process. Here’s a step-by-step guide on how to do it:
- Obtain fresh Pyrostegia venusta seeds from a reputable source. The seeds are typically found within the fruit capsules that develop after flowering. Allow the fruit capsules to fully ripen and turn brown before collecting them.
- Remove the Pyrostegia venusta seeds from the fruit capsules. It’s recommended to soak the seeds in warm water for about 24 hours to help soften their hard outer coating and enhance germination.
- Fill a seed tray or small pots with a well-draining seed-starting mix. Sow the seeds about 1 centimeter deep in the soil. Plant multiple Flamevine seeds to increase the chances of successful germination.
- Place the seed tray or pots in a warm location with bright, indirect sunlight. The ideal temperature for germination is around 20-25°C. Ensure that the soil remains consistently moist but not soggy.
- Pyrostegia venusta seeds usually germinate within a few weeks to a few months. Once the seedlings emerge, provide ample light to promote healthy growth. Gradually acclimate them to more direct sunlight over time.
- When the Orange Trumpet Vine seedlings have grown several sets of true leaves and are large enough to handle, they can be transplanted into individual pots or containers. Use a well-draining potting mix and ensure the containers have drainage holes.
- As Pyrostegia venusta is a climbing vine, it requires support as it grows. Prepare a trellis, fence, or other vertical structure for the vine to climb on. Train the young seedlings to grow along the support by gently tying them with soft plant ties or twine.

Orange Trumpet Vine prefers well-draining soil with good fertility. Flamevine can tolerate a range of soil types, including sandy or loamy soil. However, it thrives in soil that is rich in organic matter.
Before planting, amend the soil with compost or well-rotted manure to improve its structure and nutrient content.
Once established, Pyrostegia venusta is moderately drought-tolerant, but it benefits from regular watering, especially during dry periods. Water Flamevine deeply, allowing the soil to dry slightly between waterings. Avoid overwatering, as it can lead to root rot.
Orange Trumpet Vine is well-suited for warm and tropical climates. Flamevine prefers temperatures between 15-30°C. It can tolerate occasional temperature drops but is sensitive to frost. If you live in a region with colder winters, protect against freezing temperatures.
Pyrostegia Venusta Care
Pyrostegia venusta generally grows well without excessive fertilization. However, you can apply a balanced slow-release fertilizer in early spring to provide nutrients for healthy growth and blooming.
Follow the package instructions for application rates, and avoid overfertilization, as it may promote excessive vegetative growth at the expense of flowering in Orange Trumpet Vine.
Pruning Pyrostegia venusta is generally done after the blooming period. Trim back any dead or damaged branches to maintain the vine’s health and appearance.
If Flamevine becomes too unruly or outgrows its designated space, you can selectively prune or train Orange Trumpet Vine to control its growth and shape. It’s important to note that pruning too late in the season may affect next year’s blooming.
Pests and Diseases
If detected, treat them with appropriate insecticides or insecticidal soaps. Flamevine may also be susceptible to fungal diseases like powdery mildew or root rot. Ensure good air circulation, avoid overwatering, and promptly address any signs of disease.
