Trumpet vine

Trumpet vine is a vigorous woody climber from the southeastern United States, widely planted on walls and pergolas in warm-temperate regions and often naturalized. It has pinnate leaves with coarsely toothed leaflets and clusters of orange to scarlet trumpet-shaped flowers through summer.

• Hummingbirds are its main pollinators in its native range, which is why the flowers are red and tube-shaped.
• It climbs by aerial rootlets that grip masonry so tightly they can damage paint and mortar when pulled off.
• Handling the foliage causes a skin rash in some people, earning it the nickname 'cow itch vine'.

Care
Give it full sun and a very sturdy support, and prune hard in late winter to keep it in bounds and encourage flowering on new wood.
