The Rose painted calathea, with it’s clump forming habit is a species that’s more than happy growing and being displayed indoors.
likes moderately bright, indirect light, which can mean rather bright conditions indoors. Keep in mind that outdoor shade is actually brighter than most indoor space … light drops off very quickly with each foot of distance from a window.
must be kept in damp soil at all times, but definitely do not allow the plant to sit in water or in very wet soil. Think little and often as a watering policy.
The best way to water a Calathea Plant is to use distilled water, rain water, or allow your tap water to sit out over night before using it so the chemicals in it can dissipate. Keep the soil moist but never soggy and allow the top 2-3” to dry out before watering. Prefers warm to high temperatures, ideally between 18-23°C but can cope with as low as 15°C.
