Tradescantia pinetorum Greene
Pinewoods Spiderwort, Pine Spiderwort
Commelinaceae (Spiderwort Family)
Synonym(s): Aneilema pinetorum
USDA Symbol: TRPI
Clusters of blue-purple, 3-petaled flowers atop several lightly but roughly hairy stems that are mostly unbranched and erect but often bent and leaning at knee-like nodes.
This species and Western Spiderwort (T. occidentalis) were used by Native Americans as a cooked vegetable. Western Spiderwort, which grows from Montana south to Arizona and east to North Dakota and Texas, has smooth stems with several joints and bright blue to nearly rose-colored flowers. Wright's Spiderwort (T. wrightii), found on limestone slopes from central New Mexico to western Texas, has smooth stems in tufts, only about 6" (15 cm) high, and a few glandular hairs on the sepals and individual flower stalks.
The genus is named after John Tradescant (1608-1662) who served as gardener to Charles I of England.
Tradescantia species will hybridize in just about any combination.
