Calathea Zebrina

This green variety has soft velvet leaves with 'rabbit tracks' on the leaves. Watch as this plant moves it's leaves to follow the sun throughout the day!
 
Light
 
Hang or set your prayer plant near a window where it will receive indirect sunlight. Never set your plant in direct sunlight because the sun will scorch the plant’s leaves or the leaves will develop blotches or patches and fade in color intensity.1 Prayer plants are generally tolerant of lower light areas. In the winter, when the plants go into dormancy (and sometimes die back completely), provide them with bright light to maintain growth.
 
Soil
 
Prayer plants can prosper in a variety of soils, as long as they're well-draining. Typically, a traditional potting mix works fine, but you can make your own by combining two parts sphagnum peat moss, one part loamy soil, and one part perlite or coarse sand together. In addition, the soil should be acidic, with a pH of 6.0. To improve drainage, add rocks or gravel to the bottom of your pot and be sure that the pot has ample drainage holes.
 
Water
 
During their growing season, water your prayer plant frequently (whenever the top layer becomes dry) and never allow the potting soil to dry out completely. These plants are very susceptible to drought and will not survive long if left unwatered. However, to avoid fungal problems, do not let water sit directly on the leaves or let the plant get soggy. Both insufficient water and overwatering your plant can cause the leaves to turn yellow and drop.2 When watering your prayer plant, use water that is at least at room temperature, if not slightly warm.
