Peacock plant, botanically Goeppertia makoyana and still very commonly sold under its older name Calathea makoyana, is native specifically to the Atlantic rainforests of Espírito Santo state in southeastern Brazil, where it grows in the warm, deeply shaded, consistently humid understorey. It belongs to the prayer plant family, Marantaceae, and its species name commemorates Messrs. Jacob-Makoy and Co., a historic plant nursery based in Liège, Belgium, that was responsible for first introducing the species into wider Western cultivation. Like roughly 250 other species long known as Calathea, botanists reclassified this species into the revived genus Goeppertia following molecular phylogenetic research, though "Calathea makoyana" remains the name most commonly encountered in general nursery and retail settings. The species was first formally described in 1872 by the Belgian botanist Charles Jacques Édouard Morren, and it has since received the Royal Horticultural Society's Award of Garden Merit, a mark of its horticultural quality despite its genuine reputation for demanding, above-average care requirements.

The plant's common name, peacock plant, along with its equally popular alternate name, cathedral windows, both describe the same genuinely striking foliage pattern: broad, oval, pale green to nearly translucent leaves marked with two parallel rows of dark green, oval blotches running outward from the central midrib toward the leaf edges, closely echoing the pattern of a peacock's tail feather or the arrangement of stained-glass panels in a cathedral window, depending on which visual comparison a given observer favors. The leaf undersides display a rich, deep purple color, creating a dramatic two-tone effect whenever a leaf's underside becomes visible through the plant's natural nyctinastic movement — like other members of the prayer plant family, peacock plant folds its leaves upward each evening in response to darkness and unfolds them again each morning, a movement thought to help the plant reduce water loss, offer some protection from cooler nighttime temperatures, and optimize its light capture across the daily cycle in its deeply shaded native habitat.
