Calatheas are commonly known as Prayer Plants. A cool fact about them is they are called Prayer Plants because at night their leaves turn upright like prayer hands. I love Calatheas because they come in so many different varieties, you can become a Calathea collector in no time. These plants like water once a week and a sunny location such as a window sill. And that's it. Keep the soil moist to the touch but not overly wet. In other words, you almost want the soil to be dry-damp before you give them some water again. Another great thing about Calatheas is that they are non-poisonous to pets.
