Calathea insignis 'Rattlesnake'

Common Name:
Calathea (Common name applies broadly across the genus)

Description:
Calathea is a genus of tropical plants celebrated for its vividly patterned foliage, with species and cultivars showcasing an extraordinary variety of leaf shapes, colours, and markings. Native to the rainforests of Central and South America, Calatheas are renowned for their decorative leaves which often display combinations of greens, purples, silvers, and creams, along with striking undersides in deep burgundy. As part of the Marantaceae family, many Calatheas exhibit nyctinastic movement—their leaves raise and lower in response to light changes—earning them the nickname "prayer plants." These plants are best suited to indoor conditions in Melbourne, where they prefer bright, indirect light, high humidity, and consistently moist but well-drained soil. While they rarely flower indoors, their foliage alone is a showstopper. Calatheas are ideal for bathrooms or living spaces with stable temperatures and low light exposure, bringing a bold, tropical aesthetic to interior settings.
