The Calathea roseopicta, also known as a Calathea Medallion or rose-painted prayer plant, is a tropical plant native to Brazil. Calathea and the closely related Maranta grow beautifully ornate foliage. Following their circadian rhythym, Calatheas move and open their leaves up towards the sun throughout the day to maximize light intake and return to a resting position at night. Medallion plants come in different colors and patterns, but can be largely characterized by the dark red beneath the leaves and the white or pink “painted” marks on top of the leaves.
Calatheas are better suited for seasoned plant parents but will reward proper care by growing large, vibrant foliage. They grow best where they get medium to bright, indirect light. Being the tropical plants that they are, Calatheas should be watered regularly so that the soil is always at least lightly moist but never dry. Both too frequent and infrequent watering will result in burnt leaves and an unhappy plant. Mist the plant or place it in the bathroom on occasion in order to simulate a humid environment. They do well by north or south facing windows or by an east facing window with diffused light.
Although plant parents tend to have their own parenting style and each plant’s needs are different, our plant experts have a few suggestions they’ve found to be helpful overall:
The Calathea prefers medium to bright, indirect light and is sensitive to direct sunlight.
The Calathea prefer to be moist but not wet or saturated. From our experience it is easy to over water plants so make sure to feel the dirt by dipping your finger 2 - 3 inches in the soil. Yellow leaves are a sign of overwater so if you see them, simply scale down the amount of water.
Similar to humans, plants like the Calathea prefer temperatures of 65⁰ to 85⁰.
A very light feeder, apply a balanced houseplant fertilizer at half strength once every 1 - 3 months.
