Tradescantia virginiana is the type species of Tradescantia (spiderwort) native to the eastern United States. Spiderwort is commonly grown in gardens. 
Tradescantia virginiana is a herbaceous plant with alternate, simple leaves, on tubular stems. The dark green or olive green leaf blades are 130–370 mm in length and are lance-shaped; widest below the middle and tapering at both ends.
During late spring to mid-summer flowers grow out of the axil (a point where a branch or leaf is attached to the main stem. The flowers can be blue, purple, or white. Each petal is 12-20 mm in length. Toward the flower’s centre, there are 6 yellow stamens and many spidery hairs. The flowers open in the morning and close at night.
The fruit is a >7mm long capsule that when it dries splits releasing 3-6 oval to oblong, brown seeds.
The plant's root system is fleshy and fibrous and can produce occasional offshoots nearby.
