Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Erect, slender-stemmed herb, light grassy green, having 2 long, slender, spreading bracts at the base of each inflorescence, reminiscent of wings or antennae. Very lightly pubescent. Leaves: Blades linear and rolling inwards at the margins, to 13 cm long, giving the appearance of a grass blade, clasping at the base, linear venation evident. Flowers: Three petals light purple, rose, or blue flowers, subtended by 2 long, linear, spreading bracts, inflorescence single or sometimes in groups, all arising out of a single bract. Stamens feathery at the base, light purple, with bright yellow anthers. Fruits: Capsules 3-4 mm, 3-valved, with small seeds to 2 mm. Ecology: Found on granitic and limestone substrates, in wet areas on stream sides and in canyons, also found in grasslands, chaparral, mesas, and and pine forests, from 5,500-10,000 ft (1676-3048 m); flowering July-September. Notes: This lovely flower is easily recognized by its fabulous bracts, which remain even after the flower has faded. Ethnobotany: An infusion of the plant was given to livestock as an aphrodisiac. Etymology: Tradescantia is named after John Tradescant (1608-1662), English gardener to King Charles I, while pinetorum means of the pine forests.
