What is the plant

Calathea is a genus of neotropical rhizomatous herbaceous perennial plants; members of which are referred to generally as Calatheas. ‘Prayer plant’ is a colloquial term that refers to members of genus Maranta, to which genus Calathea is closely-related. In reality, they’re all considered to be ‘prayer plants.’Like a lot of low light plants, Calathea tend to grow fairly slowly. They are considered to grow at a moderately fast rate, but they will not grow and spread out over their pots and become a problem. In fact, Calathea plants usually will only grow to about 2 feet in height and then stop. After that, the only pruning you need to do is that of yellow, crispy, or brown leaves.

How to Care for the Plant

Water
Use distilled water or water that has been purified in some way to water Calathea plants. Calathea like to have moist soil or planting substances, but not soggy. They do not want lots of water, as it can drown them. When you water a Calathea plant, do not water it so much that the plant ends up sitting in standing water.
Pruning
The great news about the Calathea is that it doesn’t need pruning other than the removal of brown or yellowed leaves.
Fertilizer
Calathea do not need a lot of fertilizing, but they will flower and do well with standard houseplant fertilizer during spring, summer and fall. They especially need fertilization during periods of growth and flowering.

Sunlight
Calathea plants need bright, but not direct, sunlight to grow. This is because they grow on the floor of jungles and forests where they get limited light through the tops of the trees. In fact, direct sunlight will burn the leaves of a Calathea plant and cause it to lose its vibrant colors.
Temperature
Calathea plants do not like the cold very much. They are from tropical areas of the world and prefer temperatures between 65-80 degrees. Temperatures above and below that can cause damage to the plant, first evident in the curling of the leaves.
