This is a rampant and INVASIVE plant. Easy to grow, and is covered with brilliant blue flowers every morning from early Spring through first frosts. Flowers close in the afternoons, but are replaced each morning.

Self seeds freely and will take over open areas quickly in sun or shade.

This soujnds somewhat negative, but the plant is easy to grow, grows in all our soils, needs little care...and I have grown this pretty plant in my gardens for over 30 years. A nice plant!

I have not grown this plant. Plateau spiderwort (Tradescantia edwardsiana) is a native perennial which is endemic to Texas. Usually, it grows in canyons and in rich woods along moist alluvial terraces and ravines along the Balcones Escarpment at the eastern and southern edges of the Edwards Plateau. It also can be found in the Central Mineral Basin (Llano Uplift), ranging north on calcareous substrates almost to Oklahoma. Records verify its existence in the following Texas counties: Bandera, Bell, Bexar, Brown, Caldwell, Collin, Comal, Coryell, Dallas, Fannin, Hays, Kendall, Lamar, Llano, Medina, Palo Pinto, Real, Travis, Uvalde and Val Verde. The leaf blade is longer than the sheath which differientiates Tradescantia edwardsiana from other species of Tradescantia native to Texas. The evergreen and edible leaves are 7 to 30 cm long and 15 to 45 mm wide. They are milnutely puberulent to glabrate. The elliptic, acuminate, 6 to 9 mm long sepals are glandular-puberulent. The petals, which are 1 to 1. 2 cm long, range in color from blue to purple, white to pale mauve and rarely bright pink. Tradescantia edwardsiana blooms from February to May.
