Native to Brazil, the Rufi Barba really stands out among the Calathea's for it's smooth green feather shaped leaves on top and fuzzy, velvet purple bottoms. They feel so soft and lovely, very similar to the Lancifolia.
Keep her in a nice bright spot but out of direct sunlight so you don't burn her colourful leaves. She will be happy in a shadier spot too.
Keep her soil moist but don't over saturate her. Water when the top couple of inches of soil are dry. When you water her, make sure you drain out the water from the nursery pot to avoid her sitting in a puddle and getting root rot.
She loves moist air so if she isn't getting enough humidity you could try misting her, putting a bowl of water near her or putting her close to other plants to create their own microclimate.
She's non toxic to cats and dogs.
