What is this houseplant?

Hi Judy!
Could you kindly tell me what this houseplant is?
It would be a great help if you could teach how to water and take care of it as well.
Thank you for your help in advance! 🙂

Hi Domeneka,

Green and white Calathea Plant

Calathea Plant

Your plant is a type of Calathea Plant. Calathea Plant. All Calathea Plants are treasured for their large, oval, distinctly patterned leaves. The beautiful leaves  grow at the end of long stems and require quite a bit of care to stay looking good. It looks like you are doing an excellent job of caring for it. These plant requires high humidity to keep its leaves from getting brown edges and is not an easy-care plant,  but like many unusual houseplants, well worth the effort. You can read my plant care tips for a Calathea in the Popular HousePlant section of the website. The picture is of a different variety, but the care is the same.
