The genus Calathea—characterized by boldly marked, oblong leaves in a dazzling array of colors—includes some of the most beautiful tropical plants in the world. Due to the plants’ eye-catching stripes and veining, they’re often known by nicknames such as the zebra plant, peacock plant, or rattlesnake plant. Calatheas are also referred to as prayer plants, a common name that other species use as well.
Calatheas can be found outside in tropical environments, and they cannot tolerate cold temperatures. So elsewhere they are typically grown indoors year-round as houseplants. Moreover, calatheas can be hard to care for, as they have a reputation for being somewhat fussy about their growing conditions.
