Calathea sanguinea

Often sold under the name Calathea leopardina, this "leopard" print peacock plant is now correctly named Goeppertia concinna. As a houseplant, it is chosen for its architectural and rather sophisticated appearance. Its long leaves, striped with dark green on a light green background, pair well with contemporary decor. 

Belonging to the Marantaceae family, Goeppertia concinna is native to Brazil, where the species is reported notably in the Southeast (states of Espírito Santo and Minas Gerais). It is found in humid tropical environments, in dappled light.
This rhizomatous perennial forms an upright clump, composed of narrow to lanceolate, 20 to 30 cm long leaves, a light green traversed by broad dark green strokes arranged on either side of the central vein. In a pot, it reaches 50 cm to 1 m in height and 30 to 50 cm in width. Its growth is moderate (allow a few years to achieve a good volume). The small tubular flowers remain rare in indoor cultivation, and the plant is mainly grown for its foliage.
Good news if you live with pets: calatheas are considered non-toxic.
In the home, it thrives in bright light without direct sun, in a warm room with high humidity, with a stable temperature, ideally around 18 to 25 °C (keep above 15 °C). This plant still requires regular attention, as it reacts quickly to dry air and temperature fluctuations. It is well-suited for a bright living room, bedroom, or a well-lit bathroom.

To showcase it, play with height: a simple pot (stoneware, glazed terracotta, matte ceramic) placed on a low pedestal highlights its upright leaves, while side lighting softens its patterns. In a "tropical woodland" style display, it pairs well with Ctenanthe lubbersiana ‘Golden Mosaic’ (for the golden variegation), Anthurium crystallinum (for the velvety veining), a Fittonia ‘Mini White’ as a pot border plant, and a Boston fern (Nephrolepis) with trailing fronds. The whole arrangement works very well near a window with a sheer curtain, or in a room that is not too dry in winter.
