Campsis radicans or Trumpet Vine

Campsis radicans

Trumpet Vine



The generic name is derived from the Greek word komptein, meaning to grow crooked. The genus contains only two species: Campsis radicans, from North America, and C. chinensis, from eastern Asia. Both are liana-like climbers. The trumpet vine was introduced into Europe at a very early date. It is distinguished by its rich scarlet or orange flowers, 6 to 8 cm (2 ¼ to 3 in) long; the variety flava has somewhat larger, glowing orange blossoms. The flowers are arranged in panicles and consist of a bell-shaped calyx and a tubular, funnel-shaped corolla. They are borne over a long period, from July to September. The leaves are deciduous, opposite, odd pinnate, with sharply toothed leaflets. If provided with a support the trumpet vine will grow to a height of 10 m (33 ft) clinging to the support with its aerial roots. Other varieties cultivated include the early-flowering praecox(June) and speciosa, which is of more shrubby habit.

The trumpet vine is propagated by means of seed, root cuttings or layering. The varieties are best grafted on C. radicans rootstock. The roots penetrate to a considerable depth so it requires a deep, well-drained and nourishing soil. In order to ripen growth and produce flowers it should be planted in full sun, and in cold areas it may need protection. It is a very decorative climbing shrub for covering pergolas, walls and terraces in warm and sunny aspects.
