The Prairie spiderwort (Tradenscantia occidentalis) belongs to Commelinaceae (the Spiderwort family). It is a perennial herb that is native to central-western North America. This herb grows in prairies, along roads, edges of woods and can reach 25-60 cm in height. The stems are slender and smooth can have a bit of a zig-zag appearance due to the jointed leaf attachment. The leaves are linear, toothless and hairless, sheathing the stem. The flowers are 3-petaled, 2.5-5 cm across, blue to deep blue-violet, occasionally pink or white, and bloom in racemes from May to September. They open in the morning and typically wilt by noon on hot days.
