Tradescantia aka Spider Lily

Tradescantia, a genus of herbaceous perennial wildflowers in the family Commelinaceae, includes 85 species native to the Americas from southern Canada to northern Argentina, including the West Indies. Commonly known as inchplant, wandering jew, spiderwort, and dayflower, Tradescantia grows 30–60 cm tall and are found in wooded areas and open fields. They were introduced into Europe in the 17th century as ornamental plants and have become naturalized in regions of Europe, Asia, Africa, and Australia, and on some oceanic islands. Tradescantia are herbaceous perennials and include both climbing and trailing species, reaching 30–60 centimetres in height. The leaves are long, thin and blade-like to lanceolate, from 3–45 cm long. The flowers can be white, pink, or purple, but are most commonly bright blue, with three petals and six yellow anthers (or rarely, four petals and eight yellow anthers). The sap is mucilaginous and clear. A number of species are nyctinastic and have flowers that unfold in the morning and close when the sun shines on the flowers in the afternoon but can remain open on cloudy days until evening. The genus's many species are of interest to cytogenetics because of evolutionary changes in the structure and number of their chromosomes. They have also been used as bioindicators for the detection of environmental mutagens. Some species have become pests to cultivated crops and considered invasive, such as in Florida. This cultivar of Tradescantia is an exceptionally easy plant to care for and might surprise you with some of their delightful blossoms. They are extremely easy to propagate by stem and one plant can give rise to dozens of new ones, which makes them great for sharing. As houseplants they often trail, but will also creep along the ground if grown outdoors. Their succulent leaves make them sensitive to frost, so be sure to bring them indoors if your winter temperatures dip below freezing.
