About this plant

Tradescantia virginiana forms arching clumps of narrow, blade-like green leaves that create a relaxed fountain of foliage. From late spring into early summer, clusters of three-petaled flowers open in shades of blue to violet purple with bright yellow stamens at the center. Each bloom lasts only a day, yet new buds continue to appear along upright stems, keeping the plant in steady color for weeks. The delicate petals often close by afternoon, especially during heat.

Native to the eastern and central United States, this perennial grows naturally in meadows, woodland edges, and open prairies. In gardens it fits easily into perennial borders, pollinator plantings, and informal cottage gardens where its loose clumps weave among neighboring plants. The flowers attract bees and other beneficial insects, while the upright stems and fine foliage add gentle vertical structure during the blooming season.

Design tip

Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
