Native to the Brazilian rainforest, the Calathea Rattlesnake is a low-light plant. This gorgeous tropical plant thrives in moist, warm, semi-shady climates. So it needs lots of heat and humidity to keep this plant happy and healthy. They can also produce bright, yellow-orange flowers during late spring and early summer, if you provide the right conditions. However, it rarely blooms indoor. Of course, it’s an attention-stealer because it can grow up to 30 inches tall and sometimes more.

Calathea Rattlesnake is often sold as Calathea insignis, which is its former scientific name. Keep this in mind when buying a Calathea Rattlesnake in a nursery. Here’s everything you need to know on how to care for your Calathea Rattlesnake.
