Like many tropical plants, Calathea make a great houseplant especially in the colder months and climates, preferring the warmth of the indoors. With beautiful, bold leaf patterns you simply can't go past this one.
Moderate dappled light to low light. Keep away from direct sunlight to avoid burning the leaves.
Good drainage and regular water will help keep your Calathea looking good. Never allow the soil to dry out completely, especially during the growing season. Like most plants, water more regularly in Spring and Summer and less in Winter. Just keep an eye on the soil, if it feels dry past the first inch then give it a drink.
