Ohio Spiderwort (Tradescantia ohiensis) is a nice spring to early summer perennial that has spiky, grass-like foliage with deep blue, three petaled flowers. It is usually considered a wildflower, native to the Midwest, East and North East United States. The plant is often purchased for garden flower beds. They are grown in zones 4 to 9. The flowers only last a day, but will bloom continuously for up to six weeks. The flowers close up in the heat of the afternoon, but stay open on cool or cloudy days.
There are different accounts as to how the native plant got its name. One story says, when the stem is cut it secrets a sticky substance that resembles a spiderweb. Another theory suggests the fine hair like filaments on the flower buds looks like a spider’s web especially when covered with morning dew.
By late summer the plant will begin to look a little ragged and will eventually go dormant. The plant easily self-seeds and the clumps will grow larger with time and may need to be divided every few years. Some gardeners cut back the foliage in mid-summer and sometimes the plant will flower again in the fall.
