Hairy chaffhead (Carphephorus paniculatus) is a stunning perennial wildflower found in moist flatwoods and savannas where it tends to form large colonies. It typically blooms from late August through December, with peak flowering in October. Its beautiful fuschia flowers provide nectar for butterflies.
Hairy chaffhead’s many purple flowers are rayless, with tubular disk florets and extended stigmas. They are born in dense, terminal, elongated panicles. Flower stalks emerge from basal rosettes of oblong to elliptic, petiolate leaves that vary in length from 1 to 8 inches. Stem leaves are significantly smaller, lanceolate and sessile. They may be appressed. Margins are mostly entire. Leaf arrangement is alternate. Stems and flower stalks are reddish-purple, covered in hairs and sticky to the touch. Seeds are born in achenes.
Some botanists have separated most species of the genus Carphephorus into the genera Litrisa and Trilisa. Both genera names are anagrams of the genus Liatris, whose flowers have a similar appearance to Carphephorus flowers. Under this convention, C. paniculatus is known as Trilisa paniculata. The common names Hairy Trilisa and Deertongue are also accepted, although Deertongue is also an accepted synonym for Vanillaleaf (C. odoratissimus). “Deertongue” refers to the straplike shape of both plant’s basal leaves.
