Ohio Spiderwort (Tradescantia ohiensis)

This native perennial grows 2-4ft tall on a mostly unbranched stalk - branched near the apex. Gray-ish blue/green leaves. Tolerates a variety of growing conditions, but semi sunny with dry soil is preferred. Three petals, six yellow anthers, and a cluster of fine fibers near the base (bee belly ticklers - I joke) make up the flower.
On bright sunny days the flowers will bloom in the morning, then close in the hot afternoon. They will stay open longer on cloudy days.
These are a great source of food for long-tongued bees, and deer have been known to eat the greens.
​Makes a great addition to native wildflower gardens.
