Campsis radicans, the trumpet vine, [4] yellow trumpet vine, [5] or trumpet creeper [4] (also known in North America as cow-itch vine [6] or hummingbird vine [7] ), is a species of flowering plant in the trumpet vine family Bignoniaceae, native to eastern North America, and naturalized elsewhere. Growing to 10 metres (33 feet), it is a vigorous, deciduous woody vine, notable for its showy trumpet-shaped flowers. It inhabits woodlands and riverbanks, and is also a popular garden plant.

Description

C. radicans is a vine that climbs on trees, other plants, or structures or trails along the ground and can grow to a length of up to 10 metres (33 feet). From the main vine, rigid or woody arching vines up to 2 metres (7 feet) long extend outward. The plant can form a dense groundcover or an aggressive liana covering plants or buildings. The leaves are opposite and odd-pinnately compound, meaning there is an odd number of leaflets, with one terminal leaflet.

Leaves are up to 18 centimetres (7 inches) long with 7 to 13 leaflets that are each about 8 centimetres (3 inches) long and 4 centimetres (1.5 inches) wide. The leaflets are emerald green when new, maturing into a shiny dark green. They are ovate to broadly lanceolate and the edges are coarsely serrate. [8]

Inflorescences

The flowers come in terminal cymes of two to eight. Each flower is up to 9 centimetres (3.5 inches) long and trumpet shaped. They are orange to reddish orange in color with a yellowish throat and 5 shallow lobes bending backward. They generally appear after several months of warm weather. The flowers have no floral scent. After flowering, a long seed capsule about 15 centimetres (6 inches) long appears, eventually splitting in two to disperse its seeds. [9]

Taxonomy

The flamboyant flowering of Campsis radicans made it obvious to even the least botanically-minded of the first English colonists in Virginia. Consequently, the plant quickly made its way to England early in the 17th century.

Its botanical parentage, as a hardy member of a mostly subtropical group, made its naming problematic: according to John Parkinson, the Virginia settlers were at first calling it a jasmine or a honeysuckle, and then a bellflower; he classed it in the genus Apocynum (dogbane). Joseph Pitton de Tournefort erected a catch-all genus Bignonia in 1700, from which it has since been extricated. [10]

Etymology

The Latin specific epithet radicans means 'with stems that take root'. [11] The plant is commonly known as cow-itch vine because skin redness and itching is experienced by some people after coming in contact with the leaves. [12]

Distribution

Campsis radicans is native to the eastern United States and extreme southern Ontario in Canada. It is naturalized in parts of the western United States as well as in Ontario and southern Quebec, parts of Europe, and scattered locations in Latin America. [3] [13]

Ecology

The flowers bloom in the summer for about three months [14] [15] and are very attractive to hummingbirds such as the ruby-throated hummingbird, [9] [14] while many types of birds like to nest in the dense foliage. Halictid bees, flies, and ants also feed on the nectar of the plant's extra-floral nectaries. [9] Nectar robbing behavior has been observed to be performed by orchard orioles ( Icterus spurius ), which puncture and enlarge holes in the flower base to access nectaries. [15] Certain sphinx moths with elongate proboscises are able to successfully feed on trumpet vines while hovering in front of the flower. [16]

The flowers are followed by large seed pods. As these mature, they dry and split. Hundreds of thin, brown, paper-like seeds are released. These are easily grown when stratified. Larvae of Clydonopteron sacculana (the trumpet vine moth) feed on the seed pods. [17]

Cultivation

The trumpet vine grows vigorously. In warm weather, it puts out aerial rootlets that grab onto every available surface, and eventually expand into heavy woody stems several centimeters in diameter. It grows well on arbors, fences, telephone poles, and trees, although it may dismember them in the process. Ruthless pruning is recommended. [8] Outside of its native range this species has the potential to be invasive, even as far north as New England. [18] The trumpet vine thrives in many places in southern Canada as well.

Away from summer heat, C. radicans is less profuse of flower. A larger-flowered hybrid 'Mme Galen' was introduced about 1889 by the Tagliabue nurserymen of Lainate near Milan. [10]

The form C. radicans f. flava has gained the Royal Horticultural Society's Award of Garden Merit. [5]

A deeper red form "Flamenco" is available.

Toxicity

The plant can cause contact dermatitis. [19]

A vine is any plant with a growth habit of trailing or scandent stems, lianas, or runners. The word vine can also refer to such stems or runners themselves, for instance, when used in wicker work.

<i>Toxicodendron radicans</i> Species of plant

Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is an allergenic flowering plant that occurs in Asia and eastern North America. The species is well known for causing urushiol-induced contact dermatitis, an itchy, irritating, and sometimes painful rash, in most people who touch it. The rash is caused by urushiol, a clear liquid compound in the plant's sap. The species is variable in its appearance and habit, and despite its common name, it is not a true ivy (Hedera), but rather a member of the cashew and pistachio family (Anacardiaceae). T. radicans is commonly eaten by many animals and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed. It is a different species from western poison ivy, T. rydbergii, which has similar effects.

<span class="mw-page-title-main">Sphingidae</span> Family of insects

The Sphingidae are a family of moths commonly called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as "hornworms"; it includes about 1,450 species. It is best represented in the tropics, but species are found in every region. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802.

<i>Campsis</i> Genus of vines

Campsis, commonly known as trumpet creeper or trumpet vine, is a genus of flowering plants in the family Bignoniaceae, native to woodlands in China and North America.

<span class="mw-page-title-main">Nectar</span> Sugar-rich liquid produced by many flowering plants, that attracts pollinators and insects

Nectar is a viscous, sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, A. m. scutellata and the western honey bee.
