Ohio Spiderwort is a hardy native perennial that forms upright clumps of long, narrow, blue-green leaves. Clusters of three-petalled blue to violet flowers appear from late spring through summer. Individual flowers often open in the morning and close by afternoon, with new flowers continuing to appear over an extended period. It is an excellent choice for prairie gardens, sunny borders, meadows, and naturalized plantings.

Ohio Spiderwort forms clumps and can spread gradually by short rhizomes and self-seeding. It is generally well behaved, although it can become fairly vigorous in rich, moist soil. It is very tolerant of drought once established. It can be divided in spring or fall if the clump becomes too large. The foliage can become somewhat floppy or untidy later in summer; cutting it back is an easy way to refresh the plant. Although each flower lasts only a short time, the plant produces new flowers repeatedly, giving it a surprisingly long flowering season.
