Carolina redroot(Lachnanthes caroliana) is a perennial herbaceous wildflower. Flowers are creamy whitish-yellow and are borne in fan-like terminal clusters atop erect, pubescent stems. Leaves are flat, narrow and alternately arranged, giving the plant an iris-like appearance before it blooms.
Carolina redroot blooms from summer into fall. It occurs naturally in wet flatwoods, marshes, bogs, dome swamps, savannas and coastal swales. Its blooms are attractive to a variety of butterflies and moths; its seeds are eaten by birds; and the whole plant is favored by feral hogs, who are known to dig up and eat large patches of redroot.
The common name “redroot” comes from the reddish color of the plant’s roots and rhizomes, which were used by Native Americans for dye.
