Calathea Rattlesnake houseplants are held in high esteem due to their incredible range of colours and shapes. Native to tropical jungles of the Amazon, as houseplants they provide a centrepiece of colour and interest. In South America, Calatheas play a key role in local culture as they have a wide range of uses including transporting food, making roofs for houses, as well as for medicinal properties. While they are popular houseplants, due to habitat destruction in their native South America they are becoming increasingly threatened in the wild.
