25 Seeds Ohio Spiderwort Tradescantia ohiensis Native Wildflower

Ohio Spiderwort (Tradescantia ohiensis) is a hardy native perennial known for its striking three-petaled blue-violet blooms that open in the morning and often close by afternoon. Growing in clumps of arching, grass-like foliage, it brings a relaxed, meadow-like texture to borders, wildflower patches, and naturalized areas, and it returns reliably year after year in suitable climates.
This versatile plant works well in cottage gardens, pollinator plantings, prairie restorations, and rain gardens, where its grassy foliage provides structure even after blooming slows. It pairs nicely with coneflowers, black-eyed Susans, and native grasses, and the spent flowers can be trimmed to encourage a tidier appearance. Start seeds indoors or sow directly in a prepared bed for a low-maintenance perennial display.
