Campsis × tagliabuana 'Kudian' INDIAN SUMMER® trumpet vine - climber

Campsis

The genus Campsis consists of only two species and they both carry the energy of subtropical climbers that, over the course of evolution, learned to ascend using small aerial rootlets and to brace themselves against tree bark as if it were a natural ladder. They belong to the family Bignoniaceae, a group known for its trumpet flowers and often woody climbing habit. C. radicans originates from North America, whereas C. grandiflora comes from East Asia, an intriguing geographical split that suggests a much earlier distribution of the genus’s ancestors across the warmer regions of the Northern Hemisphere. The genus was described by João de Loureiro (1717–1791), a Portuguese missionary and botanist working in Southeast Asia, who defined it on the basis of its characteristically curved stamens, reflected in the Greek kampein, meaning “to bend”. The nomenclatural history is, however, tangled: European gardens of the 17th century were unsure where to place the plant, and it appeared under the names Bignonia, Tecoma and even Apocynum, until the 19th century finally settled the genus in its present form. In the wild it is a climber of bright woodland edges, well‑drained riverbanks and disturbed habitats, where its rapid growth and ability to root along the stems allow it to occupy space before slower woody plants can take hold.

Campsis × tagliabuana is an interspecific hybrid created by combining two species that differ both geographically and in character – the North American C. radicans and the Chinese C. grandiflora. It does not occur naturally in the wild; its origin is the result of human curiosity, horticultural intuition and a remarkably fortunate coincidence. The first documented plants appeared in the 19th century in northern Italy, where the Tagliabuana family, active in the Lombardy region, ran a nursery specialising in ornamental woody plants. It was in their horticultural enterprise that accidental pollination occurred between the two species, both of which were fashionable exotics in European collections at the time. The resulting hybrid attracted attention for its vigour, larger flowers and better adaptability to the European climate, and the Tagliabuanas began to propagate and distribute it among gardeners. The Tagliabuana family was among the respected Italian growers of the 19th century, known for their willingness to experiment with newly introduced woody plants. Their name entered botanical nomenclature in the Latinised form tagliabuana, which remains a lasting reminder of their contribution to European horticulture. The hybrid spread quickly across Europe because it combined the best qualities of both parents: the hardiness and resilience of C. radicans with the large, showy flowers of C. grandiflora. While the pure species each had their limitations – one too vigorous, the other too tender – Campsis × tagliabuana proved to be the ideal compromise, capable of growing and flowering reliably in temperate climates.
