Rhodochiton atrosanguineus is a herbaceous perennial vine [2] native to Mexico. It has been cultivated as an ornamental plant since at least 1836. [3]
Although the specific epithet is sometimes spelled atrosanguineum, chiton in Greek is masculine, [4] so the ending is correctly -us. [5]
Rhodochiton atrosanguineus is commonly known as purple bell vine or simply purple bell. [2]
All Rhodochiton species are sometimes placed in the genus Lophospermum . [6]
Its dangling flowers have a pink, bell-shaped calyx of sepals surrounding a protruding, tubular corolla of purple-black petals. [6] It has somewhat hairy, heart-shaped leaves, often with purple venation. The vine can reach three metres in length in perfect conditions, but more-likely 1.5-2.5 metres. [2] The seeds are 3mm across.
Wayne J. Elisens has outlined the somewhat confused taxonomic history of the name of this species. [7] In 1829, Joseph Gerhard Zuccarini sent seeds and a description to individuals and botanical gardens under the name "Rhodochiton volubile", considering it to be a new genus; however the name was not formally published. In 1832, Zuccarini decided that it was actually a Lophospermum , and published the name Lophospermum atrosanguineum, writing that "I held it at first to be new genus and sent the seeds obtained in the summer of 1829 to several gardens under the name Rhodochiton volubile. The figure in the Botanical Register has convinced me of the identity of the genus." [8] Not knowing of Zuccharini's change of name, in particular his publication of the epithet atrosanguineum, in 1834 Christoph Friedrich Otto and Albert Gottfried Dietrich published and illustrated Rhodochiton volubilis, an illegitimate name since a prior epithet existed. [Note 1] In 1943, Rothmaler provided a legitimate combination in the genus Rhodochiton, namely Rhodochiton atrosanguineus. [5] [Note 2]
Rhodochiton atrosanguineus has gained the Royal Horticultural Society's Award of Garden Merit. [10] [11]
This plant is undemanding if given full sun or near-full sun, well-drained soil, and general care. It will tolerate cold temperatures, but not freezing. [2]
Propagation is by seed sown in spring, or at 15-18 °C.
Plants can be pruned in late winter to manage size and shape.
Strongylodon macrobotrys, commonly known as the jade vine, emerald vine, or turquoise jade vine, is a leguminous vine endemic to the Philippines. It is a popular ornamental plant known for its cascading clusters of vibrant turquoise or greenish-blue claw-shaped flowers. Cultivating jade vine requires a tropical environment, making it a popular choice in botanical gardens and conservatories. The plant's striking appearance and limited distribution contribute to its allure among plant enthusiasts worldwide.
Rhodochiton is a genus of flowering plants within the family Plantaginaceae, native to southern Mexico and neighbouring Guatemala. They climb by means of twining leaf stalks. One of the three species, Rhodochiton atrosanguineus, the purple bell vine, is grown as an ornamental plant. All three species are sometimes included in Lophospermum.
Lophospermum is a genus of herbaceous perennial climbers or scramblers, native to mountainous regions of Mexico and Guatemala. Those that climb use twining leaf stalks. Their flowers are tubular, in shades of red, violet and purple, the larger flowers being pollinated by hummingbirds. Now placed in the greatly expanded family Plantaginaceae, the genus was traditionally placed in the Scrophulariaceae. The close relationship with some other genera, particularly Maurandya and Rhodochiton, has led to confusion over the names of some species.
Camillo Karl Schneider was a German botanist and landscape architect. A farmer's son, he was born at Gröppendorf, in the Kingdom of Saxony, and worked as a gardener at Zeitz, Dresden, Berlin and Greifswald. Returning to Berlin to work in the City Parks Department, he assisted in editorial work for the periodical Gartenwelt, which led to his employ as a landscape assistant in Darmstadt and Berlin. In 1900, he moved to Vienna, where he practiced as a freelance architect and writer, travelling extensively through Europe. In 1904 he published his first books, including the beginning of his tome Illustrated Handbook of Broad-leaved Trees, which he completed in 1912. However, the manuscript of what should have been his magnum opus, a study of the genus Berberis, was destroyed in a bombing raid on Berlin in 1943. In 1907 he created the specimen series Plantae hungaricae 1907 distributed as an exsiccata-like series.
Salvia is the largest genus of plants in the sage family Lamiaceae, with nearly 1,000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, Salvia is part of the tribe Mentheae within the subfamily Nepetoideae. One of several genera, commonly referred to as sage, it includes two widely used herbs, Salvia officinalis and Salvia rosmarinus.
Asarina is a flowering plant genus of only one species, Asarina procumbens Mill. the trailing snapdragon, which is native to France and Spain and introduced in Germany, Switzerland, Austria and Hungary. Originally placed in the Scrophulariaceae, the genus has more recently been moved to the Plantaginaceae. Species from North America formerly placed in the genus Asarina are now placed in Holmgrenanthe, Lophospermum, Mabrya and Maurandya, as well as Neogaerrhinum. Asarina is now regarded as exclusively an Old World genus.
Maurandya is a genus of flowering plants in the family Plantaginaceae, native to Mexico and the south west United States. They sprawl or climb by means of twining leaf stalks. One of the four species, Maurandya barclayana, is widely cultivated as an ornamental plant.
Billie Lee Turner was an American botanist and professor of botany at the University of Texas at Austin where he also directed the botany research programme and herbarium.
Holmgrenanthe petrophila is a rare perennial desert plant in the plantain family (Plantaginaceae), and the sole species of the genus Holmgrenanthe. It forms low mats of branched stems growing from a woody base. The leaves have small spines along their edges. The solitary yellow flowers are tubular with five free lobes at the end, the upper two pointing backwards, the lower three projecting forwards. The species is known only from about ten locations, most in the Titus Canyon and the adjacent Fall Canyon, all within the Californian section of Death Valley National Park. It grows in limestone crevices on the canyon walls, often on the north face.
Lophospermum erubescens, known as Mexican twist or creeping gloxinia, is a climbing or sprawling herbaceous perennial plant, native to the Sierra Madre Oriental mountains of Mexico, where it is found along forest margins or canyon walls. It climbs by means of twining leaf stalks. Wild plants have pink and white tubular flowers, although other colours are found in cultivation. It has been cultivated as an ornamental plant since at least 1830. Although not frost-hardy, it will survive if its base and roots are protected from freezing in the winter. It has escaped from cultivation and become naturalized in tropical and subtropical areas of the world.
Lophospermum scandens is a scambling or climbing herbaceous perennial native to south central Mexico, with red-violet and white tubular flowers and toothed heart-shaped leaves. It grows at elevations between 1,400 and 2,400 m in dry habitats, including deciduous oak forests and recent lava flows. The long-tubed flowers are pollinated by hummingbirds. It has been used in gardens as an ornamental plant since the mid-19th century. Its roots require protection from frost in regions where this occurs in the winter. Hybrids of L. scandens are also grown.
Mabrya is a genus of flowering plants in the plantain family, Plantaginaceae. It consists of herbaceous perennials with brittle upright or drooping stems, found in dry areas of Mexico and the southern United States.
Maurandya scandens, also known as trailing snapdragon and snapdragon vine, is a climbing herbaceous perennial native to Mexico, with snapdragon-like flowers and untoothed leaves. It is grown as an ornamental plant in many parts of the world, and has commonly escaped from cultivation to become naturalized. Other names for this plant include creeping snapdragon, vining snapdragon, creeping gloxinia and chickabiddy.
Rhodochiton hintonii is a climbing or sprawling herbaceous perennial native to the state of Guerrero in Mexico. It has dangling flowers, with a bell-shaped calyx and dark purple petals forming a tube. Unlike the better known Rhodochiton atrosanguineus, the petal tube is asymmetrical with two "lips".
Rhodochiton nubicola is a climbing or sprawling herbaceous perennial native to the state of Chiapas in Mexico and to Guatemala, where it grows in cloud forests at between 1,300 and 3,000 m. It has dangling flowers, with a bell-shaped calyx and dark purple petals forming a tube. Unlike the better known Rhodochiton atrosanguineus, the petal tube is asymmetrical with two "lips".
Lophospermum purpurascens is a climbing or scrambling herbaceous perennial native to Mexico, occurring in the states of Oaxaca, Veracruz and possibly Puebla. It has tubular flowers, white at the base and dark purple elsewhere. It was first described by Wayne J. Elisens in 1985. The epithet purpurascens means purplish or becoming purple.
Mabrya geniculata is a mat-forming herbaceous perennial native to the Mexican states of Sonora and Chihuahua. It has pale yellow tubular flowers. It was first described in 1894 by Benjamin L. Robinson and Merritt L. Fernald in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985.
Mabrya flaviflora is a mat-forming herbaceous perennial native to a small area in Baja California Norte, Mexico. It has pale yellow tubular flowers. It was first described by Ivan M. Johnston in 1924 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985 as Mabrya geniculata subsp. flaviflora. It was restored to a full species within Mabrya by David A. Sutton in 1988. The epithet flaviflora means yellow-flowered.
Mabrya rosei is a mat-forming herbaceous perennial native to the Mexican states of Jalisco and Zacatecas. It has tubular flowers, whitish at the base and red to red-violet at the apex. It was first described by Philip A. Munz in 1926 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. Munz did not explain the origin of the epithet rosei but listed the collector of the type specimen as Joseph Nelson Rose.
Mabrya erecta is an upright herbaceous perennial native to Mexico – the states of Chihuahua, Coahuila, Durango, Nuevo León and possibly México. Unlike other members of the genus Mabrya, it does not form mats. It has tubular flowers, whitish at the base and pink to red-violet at the apex. It was first described by William B. Hemsley in 1882 in the genus Maurandya and transferred to Mabrya by Wayne J. Elisens in 1985. The epithet erecta means erect or upright.
