About Trumpet Vine
Botanically, Campsis radicans is a fast-growing climber in the Bignoniaceae family. It reaches around 10 m tall and 5 m wide at maturity, with deciduous foliage. Orange and red flowers appear for much of the year.
Where to grow Trumpet Vine
Trumpet Vine suits warm-temperate, cool-temperate and subtropical climates and grows best in full sun. It is frost hardy and shrugs off cold winters.
Soil & planting
Trumpet Vine does best in loamy, clay and free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool. For a screen, space plants about 3 m apart.
Watering & feeding
Trumpet Vine performs well with relatively little water once established. Refresh mulch and provide a modest balanced feed at the start of spring. Keep a newly planted specimen evenly watered through its first season; established plants can then follow the water needs above.
Pruning & care
Prune Trumpet Vine after flowering to keep it compact and encourage the next flush of blooms. It clips well, so trim two or three times a year for a formal finish. Overall it is moderate maintenance.
Using Trumpet Vine in the garden
Trumpet Vine earns its place for a shade tree, a feature or specimen planting, drawing nectar-feeding birds into the garden and a fast screen or informal hedge.
Companion planting & design
Combine Trumpet Vine with plants that share its preference for low water use and warm-temperate climate. Use an odd-numbered group where space allows, or repeat it at intervals through a longer bed.
Good to know
It is thornless and easy to handle. Be aware it can self-seed or spread into bushland in some regions — check it is not a declared weed in your area before planting.
