From there the type species, Tradescantia virginiana, was brought to England in 1629. Tradescant the Younger mounted three expeditions to the new colony of Virginia. 1570s – 1638) and John Tradescant the Younger (1608–1662), who introduced many new plants to English gardens. The scientific name of the genus chosen by Carl Linnaeus honours the English naturalists and explorers John Tradescant the Elder (c. The sap is mucilaginous and clear.Ī number of species have flowers that last for only a day, opening in the morning and closing by the evening. The flowers can be white, pink, purple or blue, with three petals and six yellow anthers (or rarely, four petals and eight anthers).
The leaves are long, thin and blade-like to lanceolate, from 3–45 cm long (1.2–17.7 in). Tradescantia are herbaceous perennials and include both climbing and trailing species, reaching 30–60 centimetres (0.98–1.97 ft) in height. Some species have become pests to cultivated crops and considered invasive. They have also been used as bioindicators for the detection of environmental mutagens. The genus's many species are of interest to cytogenetics because of evolutionary changes in the structure and number of their chromosomes. Some species have become naturalized in regions of Europe, Asia, Africa, and Australia, and on some oceanic islands. They were introduced into Europe as ornamental plants in the 17th century and are now grown in many parts of the world. Tradescantia grow 30–60 cm tall (1–2 ft), and are commonly found individually or in clumps in wooded areas and open fields. Members of the genus are known by many common names, including inchplant, spiderwort, and dayflower. Tradescantia ( / ˌ t r æ d ə ˈ s k æ n t i ə/ ) is a genus of 85 species of herbaceous perennial wildflowers in the family Commelinaceae, native to the Americas from southern Canada to northern Argentina, including the West Indies.
