Habit

Pyrostegia venusta, also commonly known as flamevine[2] or orange trumpetvine, is a plant species of the genus Pyrostegia of the family Bignoniaceae originally endemic to southern Brazil, Bolivia, northeastern Argentina and Paraguay, but is now a popularly cultivated garden species.[3][4]

Description[]

It is an evergreen, vigorously expanding climber that reaches up to 5 m in height. The foliage is made up of green leaves that have 2 to 3 leaflets, opposite, 4 to 8 cm long and with 3-branched tendrils.[5]

The orange flowers, which appear from winter to spring, are densely packed together and are 5 to 9 cm long. They are pollinated by hummingbirds. The fruits are smooth 3cm long brown capsules.

Cultivation[]

The plant is sensitive to cold winds and prefers sunny, sheltered locations. Frost hardiness zones is 9–11. It is resistant to soil salinity.

The plant has powerful twiners which will cling to almost anything, including brick walls. It can be grown from semi-hardwood cuttings taken in summer, autumn or winter.

It is naturalised in eastern Australia, eastern Africa and south-eastern USA.[6]

Taxonomic history[]

The species was first described by John Miers in 1863.

Etymology[]

Venusta means 'beautiful', 'charming', or 'graceful'.[7] Pyrostegia" from the Greek pyros means 'fire', relating to the colour of the flowers and the shape of the upper lip, and stegia means 'covering'. When the flowers cover the roof, it looks like it's on fire. ▼
