Chinese Trumpet Creeper Plant Info
Chinese trumpet creeper vines (Campus grandiflora) can be grown in USDA zones 6-9. They grow rapidly once established and can attain lengths of 13-30 feet (4-9 m.) in an ideally sunny area. This vigorous woody vine bears blossoms in the early summer in a profusion of 3-inch (7.5 cm.) red/orange blossoms.
The trumpet-shaped flowers are borne off of new growth beginning in early June and the profusion lasts for about a month. Thereafter, the vine will sporadically blossom throughout the summer. Hummingbirds and other pollinators flock to its blooms. When the blossoms die back, they are replaced by long, bean-like seed pods that split open to release the double winged seeds.
It is an excellent vine for full sun exposures growing on trellises, fences, walls, or on arbors. As mentioned, it is not nearly as aggressive as the American version of trumpet creeper vine, Campsis radicans, which spreads invasively through root suckering.
The genus name is derived from the Greek ‘kampe,’ which means bent, referring to the bent stamens of the flowers. Grandiflora stems from the Latin ‘grandis,’ meaning large and ‘floreo,’ meaning to bloom.
