Chinese Trumpet Creeper Campsis grandiflora

Other Common Name(s):

Phonetic Spelling
KAMP-sis gran-dih-FLOR-uh
Description

Chinese trumpet creeper is a deciduous, perennial vine that climbs by aerial rootlets. In its native China, it can be found on hillsides and roadsides, climbing into trees and growing on rocks. The genus name comes from the Greek word kampe meaning “bent” in reference to the bent stamens of the flowers. The species epithet is Latin for “large-flowered.”

Chinese trumpet creeper is a hardy plant. 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. A plant can take some years to establish before it starts to flower. It flowers on new growth in summer. Once they are mature, they can be pruned in the spring to keep the vine within bounds. To stimulate new flower formation, remove spent flowers to prevent the plant’s energy from being diverted to the formation of fruits. 

Chinese trumpet creeper grows rapidly, although it is less aggressive than the native trumpet vine (C. radicans) and has fewer rootlets. It will need support as it climbs, partly twining with few aerial roots. Without support, it will scramble on the ground and form an effective ground cover, rooting along the branches. The trumpet creepers typically found in the trade are likely to be Campsis x tagliabuana, a hybrid between C. grandiflora and C. radicans

This plant can be used on an arbor, pergola or trellis as an effective vertical screen or accent. It is appropriate for Asian gardens but would also be suitable for pollinator gardens or cottage gardens.

Diseases, Pests and Other Problems: No known serious pest or disease disease problems. The fresh young growth in spring is often damaged by late frosts and may need protection. Plants can spread somewhat aggressively, particularly in rich, fertile soils, by suckering from underground runners.
