We received a gift of a plant. It stands about four feet from the floor. The largest leaf is about 18 inches long and about 8 inches wide at the widest point. The leaves are shiny and a strong deep green with black sections. See the pictures. Please help as we want to know exactly how to care for it.
it looks like a type of calathea (maranta family). The leaves look like they have been sprayed with a leaf shine, you should wipe or rinse them off. This product is designed for cut greens in arrangments not for living plants. It usually causes the leaves to yellow after a while if they have been sprayed with the leaf shine.
