Trumpet creeper is also known as the trumpet vine and is botanically classified as Campsis radicans from the Bignoniaceae (bignonia) family of plants. It is a fast growing vine that can get up to 40 feet long. It has aerial roots that attach freely to many surfaces and can climb well against trees and trellises.
Leaves are compound, bright green, and 4 to 12 inches long. Each has between seven and 15 leaflets that are 1 to 4 inches long. Flowers are yellow-orange or red, bloom in the summer, and are trumpet-like. They are tubular and get 3 to 4 inches long. After flowers bloom all summer into the fall the seed capsules will be on the vine throughout winter.
Grow a Campsis radicans in sun for the best flowers to form. It will also tolerate shade conditions. Soils should be rich and moist for the best growth, but it can also adapt to poor soils as well. Regular watering will be needed for the best growing vine.
Hardiness and Propagation
You can grow a trumpet creeper in the USDA hardiness zones of 6 through 10 without a problem. To propagate it, use seeds and sow them straight into the ground, or use suckers that are easy to transplant from the roots that are growing from the plant.
The trumpet creeper vine can be a skin irritant and has been referred to as the "cow-itch vine." Contact dermatitis in the form of burning and red skin can occur in some individuals. Care also needs to be taken to control the spread of this vine as it can become invasive in the best conditions.
Trumpet creeper is a great vine to plant to attract butterflies and hummingbirds into the landscape. The vine has rich amounts of nectar that the hummingbirds and butterflies will flock to get. It has been used to grow quickly on arbors for a garden focal point. They are typically used as a fast growing flower producing vine to go wherever fences and borders need rich foliage and color.
