Ctenanthe, commonly called the never never plant, encompasses a genus of roughly fifteen recognized species native to the tropical rainforests of Brazil, with some species also found in parts of Central America including Costa Rica. The genus belongs to the prayer plant family, Marantaceae, placing it alongside calathea, maranta, and stromanthe as close relatives, and was first formally described in 1884; the genus name comes from the Greek words "ktenos," meaning comb, and "anthera," referring to anther, a reference to a comb-like structure found in the plant's floral anatomy. Like its prayer plant relatives, Ctenanthe displays nyctinasty, the daily rhythmic folding and unfolding of its leaves in response to changing light — each evening, the elliptical, herringbone-patterned leaves rise upward into a folded, near-vertical position resembling praying hands, then relax back down and outward again as daylight returns each morning, a behavior thought variously to help direct rainfall toward the roots, offer some protection from cooler nighttime temperatures, or optimize the plant's light capture across the daily cycle in its native shaded forest understorey.

Several species within the genus are commonly grown as houseplants, each with distinct foliage patterns. Ctenanthe setosa displays elliptical leaves marked with a herringbone pattern of dark green curved bands set against a silver-white background, with striking purple undersides visible whenever the leaves fold up at night; its popular cultivar 'Grey Star' offers a more subdued, whisper-thin herringbone pattern against silver-gray foliage, paired with purple stems and leaf undersides. Ctenanthe burle-marxii, commonly called never never plant or fishbone plant, features oval leaves with a broader, bolder herringbone pattern and rounded, blunt leaf tips, named in honor of the celebrated Brazilian landscape architect Roberto Burle Marx. Ctenanthe oppenheimiana, sometimes called giant bamburanta, grows considerably larger and more dramatically than its smaller relatives, and its popular 'Tricolor' cultivar displays a striking combination of dark green, creamy white, and reddish-burgundy coloring, though this species has a genuine reputation for being more demanding to grow well, generally requiring more consistent warmth and humidity than the average home reliably provides — some specialist growers recommend cultivating it specifically under glass or in a dedicated humidity cabinet to maintain the constant conditions it prefers. Ctenanthe lubbersiana, another commonly grown species and sometimes called bamburanta, offers dark green leaves streaked with cream or yellowish-green variegation on stems that resemble slender bamboo canes; in its native Brazilian habitat it can form bushes reaching nearly six feet tall, though as a houseplant it typically stays considerably more compact, generally in the range of two to three feet.
