Pyrostegia venusta, also commonly known as flamevine[2] or orange trumpet vine,[3] is a plant species of the genus Pyrostegia of the family Bignoniaceae originally native to southern Brazil, Bolivia, northeastern Argentina and Paraguay; today, it is also a widely cultivated garden species.

The foliage is made up of opposite, pinnate leaves with two or three, 4 to 8 cm leaflets, and a 3-branched tendril, which all arise together from the end of the leaf petiole.

The plant is sensitive to cold winds and prefers sunny, sheltered locations.

The plant has forked tendrils, which will cling to any rough surface, including brick walls.

[7] "Pyrostegia" is from the Greek pyros 'fire', relating to the colour of the flowers and the shape of the upper lip, and stegia 'covering'.
