Ionactis linariifolia grows across much of eastern and central North America from Florida north as far as Québec and New Brunswick, and west to extreme eastern Texas.[3] It is found in a variety of habitats such as moist sites, oak pine woods, ridges, and bluffs.[2]
Ionactis linariifolia is an herb up to 70 cm (28 inches) tall. Leaves are green, long and narrow, up to 4 cm (1.6 inches) long. The plant usually produces several flower heads in a flat-topped array. Each head has blue, white, or violet ray flowers surrounding numerous yellow disc flowers.[4]
It was initially classified by Carolus Linnaeus as Aster linariifolius,[5] known as the stiff-leafed aster.[6] Ionactis was classified as a separate genus by Edward Lee Greene in 1897.[7]
