All you need to know about growing campsis, also known as trumpet vines, in our Grow Guide.
Trumpet vines, commonly referred to by their botanical name Campsis, are deciduous woody climbers with spectacular red, orange or yellow tubular flowers that bloom from late summer through to autumn. They need a large space to grow, ideally a south-facing wall or a pergola in full sun.
Campsis radicans will quickly cover a framework, but annual pruning helps control its growth. Although it originates from the south-eastern US, this sun-loving perennial is reasonably hardy throughout most of the UK, if grown in a sheltered, sunny spot.
Campsis grandiflora, also known as the Chinese trumpet creeper, is another vigorous grower (though not as vigorous as Campsis radicans), with clusters of deep orange-red trumpet flowers in late summer and autumn. Although native to Japan and China rather than the US, the Chinese trumpet creeper shares many characteristics with its American cousin, including a preference for sunny locations.
The main difference between the two species is that Chinese trumpet vine has very few aerial roots, so will need tying on to its support. In contrast, Campsis radicans produces many aerial roots and should be self-supporting once established.

How to prune campsis
Annual pruning will help control the spread of the vine and create a strong framework of woody branches from which flower-bearing shoots will grow. Formative pruning involves creating a strong woody framework by cutting stems back to 15cm above the ground after planting to encourage new growth. Tie two or three of the strongest resulting shoots into the trellis or other support structure, and remove the rest.
After two or three years, the framework of stems should be complete. In subsequent years, spur-prune the sideshoots back to within two or three buds of the permanent framework in late winter or early spring. Remove any diseased or damaged stems. Campsis can also be cut back hard if it has become overgrown. In February or March, prune all stems back to 30cm from the base, and then train the vine as you would a new plant.
How to care for campsis
Keep your trumpet vine well watered during the first year. They have fairly good drought tolerance once established, but grow better if watered in dry periods. Plants in containers benefit from regular watering and feeding with a high potassium liquid feed, such as tomato fertiliser or homemade comfrey tea, to encourage flowering. Adding a layer of mulch once a year in spring or autumn helps retain moisture in the soil and prevent plants drying out.
Campsis can take a few years to flower freely after planting. If you have a mature trumpet vine that is not flowering, it may be as a result of being planted in too shady a spot, being fertilised with nitrogen-rich feed that encourages vegetative growth at the expense of flowers, or being pruned too late in spring. Trumpet vines require full sun to ripen new wood and help the plant produce a profusion of blooms.
If foliage starts to turn yellow or brown, or leaves fall off, it is worth checking the that rootzone is not too dry or too wet. Trumpet vines can be overwintered successfully in many parts of the UK, provided they are grown in a sheltered location such as against a sunny wall.

FAQ
Is Chinese trumpet vine invasive?
Trumpet vine is listed as invasive in some areas of the United States, because when it escapes from cultivation, it can choke out other species. 2 The USDA lists trumpet vine (trumpet creeper) as a noxious weed.
How do you take care of a Chinese trumpet vine?
It grows best in well-drained loam or moist soil in a sunny position. It does not tolerate shade. It will tolerate coastal conditions and is mildly resistant to damage from deer. Chinese trumpet creeper requires hot summers for best flowering.
Does trumpet vine come back every year?
It’s so vigorous a grower it always comes back. Early in spring before new growth appears, cut the plant nearly to the ground, because aggressive pruning is the only way to keep it from taking over your yard. Deadhead trumpet vine flowers after they bloom to keep the plant from reseeding and spreading.
Is trumpet vine toxic to touch?
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems, however, the species is an aggressive spreader. Trumpet vine is also commonly known as cow-itch vine because some people experience skin redness and itching after coming in contact with the leaves.
