Synonyms[1]

Vinca (/ˈvɪŋkə/;[2] Latin: vincire "to bind, fetter") is a genus of flowering plants in the family Apocynaceae, native to Europe, northwest Africa and southwest Asia.[3][4][5][6] The English name periwinkle is shared with the related genus Catharanthus (and also with the common seashore mollusc, Littorina littorea).

Description[edit]

Vinca difformis in habitat, Cáceres, Spain

Vinca plants are subshrubs or herbaceous, and have slender trailing stems 1–2 m (3.3–6.6 ft) long but not growing more than 20–70 cm (8–27.5 in) above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely. The leaves are opposite, simple broad lanceolate to ovate, 1–9 cm (0.5–3.5 in) long and 0.5–6 cm (0.20–2.36 in) broad; they are evergreen in four species, but deciduous in the herbaceous V. herbacea, which dies back to the root system in winter.[7][8]

The flowers, produced through most of the year, are salverform (like those of Phlox), simple, 2.5–7 cm (0.98–2.76 in) broad, with five usually violet (occasionally white) petals joined together at the base to form a tube. The fruit consists of a pair of divergent follicles; a dry fruit which is dehiscent along one rupture site in order to release seeds.[7][8]

Gardens[edit]

Two of the species, Vinca major and Vinca minor, are extensively cultivated as a flowering evergreen ornamental plant. Because the plants are low and spread quickly, they are often used as groundcover in garden landscapes and container gardens. They are also traditionally used in older cemeteries as an evergreen maintenance-free ground cover.[9] Many cultivars are available, with different plant, leaf, and flower - colors, sizes, and habits.

Invasive plant species[edit]

Although attractive, both Vinca major and Vinca minor may be invasive in some regions where they are introduced species because of the rapid spreading resulting in choking out native plant species and altering habitats. Areas affected include parts of Australia, New Zealand, Canada, and the United States, especially coastal California.[10][11]

Medicinal use[edit]

The vinca alkaloids include at least 86 alkaloids extracted from plants in the genus Vinca.[12][13][14] The chemotherapy agent vincristine is extracted from Vinca rosea (current name Catharanthus roseus),[15][16][17] and is used to treat some leukemias,[18] lymphomas,[19] and childhood cancers,[20] as well as several other types of cancer and some non-cancerous conditions. Vinblastine is a chemical analogue of vincristine[13][16][21] and is also used to treat various forms of cancer.[22] Dimeric alkaloids such as vincristine and vinblastine are produced by the coupling the smaller indole alkaloids vindoline and catharanthine.[13][23] In addition, the nootropic agent vincamine is derived from Vinca minor. Vinorelbine, a newer semi-synthetic chemotherapeutic agent, is used in the treatment of non-small-cell lung cancer[16][24] and is prepared either from vinca natural products leurosine[25][26] or catharanthine and vindoline,[16][27] in both cases by first preparing anhydrovinblastine.[15][16][27]
