Campsis radicans Trumpet Creeper, Trumpet Vine1

Edward F. Gilman2

Introduction

Trumpet vine climbs to 30 feet or more when given support (Fig. 1). The brilliant orange flowers are borne in summer and are often visited by hummingbirds. They will hang down from an arbor or trellis making a wonder “wall” or “ceiling” in a garden. Rapid growth makes training easy, but regular pinching and pruning is required to establish this vine on a structure. The invasive nature of the plant makes it hard to get rid of once it is established in the yard. Ants often live on trumpet vine and are sometimes found objectionable by gardeners. The thick, woody stem can grow between wooden house siding and destroy it. It is best suited for planting at the base of an arbor or trellis. It can also be used in a container where it will cascade over the side.

Use and Management

Like many vines, trumpet vine flowers best in a full sun location. It grows but flowers poorly in a shaded location. It will do fine in any soil except those kept continually wet and flooded.

There are several cultivars: 'Atropurpurea' - large, dark red flowers; 'Speciosa' - bushy growth habit; 'Flava' - yellow flowers; 'Praecox' - blooms earlier.

Planthoppers may occasionally feed on trumpet vine. The insects generally cause no serious damage so controls are not needed.

Pests and Diseases

Leaf spot caused by various fungi may be seen but are not serious.

Powdery mildew causes a white powdery growth on the leaves.
