Calathea comes in a variety of foliage colors. Calathea roseo-picta offers alternating green colors on the top side of the leaves with reddish-purple undersides. In addition to being a lovely houseplant, it has also been used traditionally as an herbal medicine. "Leaves boiled in water are used as a medicine to treat mouth sores," says Coelho.
A common issue when growing calathea is its tendency to have browning leaf tips and edges. This is caused by a sensitivity to fluoride and salts in regular tap water. It can be remedied by providing high humidity (mist or set plants on a moist pebble tray, especially in the dry heat during wintertime) and watering plants with distilled water or rain water. Keep soil moist and place plants in bright, indirect light.
