Calathea is a genus of neotropical rhizomatous herbaceous perennial plants that are known for the unique leaf movements of patterned foliage. In the tropics, colorful calathea leaves are used for handicraft and food wrapping. Because of the diversity of the leaf shapes, baskets are weaved with the lanceolate leaves, and food is wrapped with the wider leaves. These colorful leaf markings also make them popular houseplants, and their popularity has been growing.
Calatheas are part of the ‘prayer plant’ family, Marantaceae. The prayer plant nickname stems from the daily movements of the plants leaves, known as nyctinasty. They move their leaves by changing the water pressure in their pulvini, the swollen nodes at the base of the leaf, along the leaf stalk (petiole). It is believed that these movements are meant to follow the sun’s movement in the sky in order to maximize light absorption.
Sunlight |
Calatheas thrive in medium to bright indirect light, but can tolerate low indirect light. |
Water |
Water every 1-2 weeks, allowing soil to dry out half way down between waterings. Expect to water more often in brighter light and less often in lower light. |
Humidity |
Calatheas prefer higher humidity if possible. Consider incorporating a fine-mist mister or humidifier to boost humidity level indoors. |
Temperature |
Like most popular houseplants, calatheas prefer temperatures in the 65°F-85°F range (18°C-30°C), similar to their tropical native habitat. It’s best not to let the temperature go below 60°F (15°C) to avoid cold damage. |
Calatheas are pet-friendly! They are considered non-toxic, making them safe to keep around cats and dogs. However, the best practice is to keep houseplants out of reach of small children and curious pets just in case.
