Calathea Musaica, aka Calathea Network, is one of the most interesting, among the 300 different types of Calathea plants, with unique mosaic-like markings on the leaves. They grow relatively slow, but can eventually reach a height of around two feet if allowed to grow by repotting regularly. Calathea has a habit of folding up their leaves during the night, a phenomenon called nyctinasty.
