Description
The American trumpet vine (Campsis radicans) is a summer-green climber native to eastern North America. It climbs independently up to 10 m using adhesive roots, attaching to walls, fences, and pergolas. From July to September its trumpet-shaped flowers blaze in vivid orange‑red, attracting bees, bumblebees, and butterflies. In the garden it serves as an imposing screen on a south-facing wall or as a summer focal point over a trellis. Cultivars such as ‘Flava’ (yellow) and ‘Atropurpurea’ (dark red) allow fine colour adjustment.
Care instructions
Plant in full sun, warm, wind‑protected spot, an south-facing wall that stores heat is ideal. The soil should be well‑drained and moderately fertile; the plant does not tolerate waterlogging. In the first two to three years after planting, protect the roots in winter with a mulch layer of leaf or bark mulch until the plant is well established. A vigorous pruning in early spring is well tolerated and encourages more abundant flowering.
