Description

Spiderwort (Tradescantia ohiensis)

Tradescantia ohiensis is the most common Spiderwort species, in the wild, in the eastern United States. Its native range extends north to Wisconsin, Michigan, and slightly into Ontario, west to Texas and Kansas, south to Florida, and northeast to Massachusetts.

Spiderworts is a genus of an estimated 71 species of perennial plants in the family Commelinaceae, native to the New World from southern Canada south to northern Argentina. They are weakly upright to scrambling plants, growing to 30-60 cm tall, and are commonly found individually or in clumps in wooded areas and fields. The leaves are long, thin and bladelike to lanceolate, from 3-45 cm long. The flowers are white, pink or purple but most commonly bright blue, with three petals and six yellow anthers. The sap is mucilaginous and clear. A number of the species flower in the morning and when the sun shines on the flowers in the afternoon they close up, but the flowers can remain open on cloudy days until evening.

The genus takes its name from John Tradescant the elder, an 17th century English plant collector and nurseryman.

The cells of the stamen hairs of some Tradescantia are colored blue, but when exposed to sources of ionizing radiation such as gamma rays, the cells mutate and change color to pink; they are one of the few tissues known to serve as an effective bioassay for ambient radiation levels.
