Pyrostegia (Flame Vine)
Pyrostegia venusta
📖 About this plant
Pyrostegia venusta, commonly called Flame Vine, Flaming Trumpet, or Orange Trumpet Vine, is one of the most spectacular flowering climbers in the world — when in bloom from winter to spring, the plant is covered in such profusion of brilliant orange tubular flowers that it appears to be on fire, hence the common name “Flame Vine”. Native to Brazil, Argentina, and Paraguay, Flame Vine has become a beloved ornamental climber in Indian gardens — particularly in Bangalore, Pune, and other cooler regions where the winter bloom provides spectacular colour when most other climbers are dormant. The plant produces dense clusters (corymbs) of 15-30 bright orange, tubular flowers at the branch tips — each flower is 5-7 cm long with curved-back petals, giving the cluster a fiery appearance. The bloom lasts 4-6 weeks and is so prolific that the entire plant is hidden under a blanket of orange. The plant is a vigorous, evergreen climber that needs strong support — a pergola, arch, fence, or large trellis. It can also be grown as a sprawling ground cover or cascading from a large container. Beyond ornamental value, Pyrostegia has medicinal uses in traditional Brazilian and Indian medicine — the leaves are used to treat diarrhea, respiratory conditions, and skin diseases. Modern research has confirmed antimicrobial and anti-inflammatory properties. The plant is a magnet for sunbirds, butterflies, and bees when in flower — the tubular orange flowers are particularly attractive to sunbirds, which are the primary pollinators. Flame Vine is one of the easiest climbers to grow — it tolerates heat, drought, poor soil, and urban pollution.

💡 Care tips
- Plant in full sun for maximum flowering — shade reduces bloom dramatically.
- Provide a strong trellis, pergola, arch, or fence — Pyrostegia is a vigorous climber that needs substantial support.
- Water regularly during the growing season
- reduce in winter.
- Apply compost or balanced fertilizer every 6-8 weeks during the growing season.
- Prune hard after flowering (spring) to control size and shape — Pyrostegia tolerates severe pruning and blooms on new growth.
- The plant can become aggressive — prune regularly to keep it within bounds and remove suckers.
- The plant is perfect for covering pergolas, arches, large fences, or as a cascading ground cover on slopes.
- In containers, use a 16-18 inch pot with a substantial trellis.
- The plant is drought-tolerant once established and suitable for low-maintenance landscapes.
- The spectacular winter-spring bloom attracts sunbirds, butterflies, and bees — plant near windows or seating areas to enjoy the show.
- Pyrostegia is one of the easiest and most rewarding climbers for tropical and subtropical regions.
