Calathea (Syn. Goeppertia) is a genus of plants belonging to the family Marantaceae. There are several dozen species in this genus. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. They are commonly called calatheas or (like their relatives) prayer plants.
Ideal soil conditions for Calathea should be porous and well draining. Drainage is very important for Calatheas due to root rot. Root rot is a common problem with many house plants that do not have effective drainage which ultimately kills the plant. A light porous soil will ensure that the plant's delicate root system is not "drowning".
