Bright indirect light is preferred for Burle Marx plants. However, they can survive in low light environments. Although, growth will be quicker in brighter light.
These beauties are native to the rainforests of South America. Thus, they love filtered light. Outdoors, Burle Marx plants prefer at least partial shade.
However, too much light or direct sunlight on your Burle Marx leaves can cause sunburn. It may appear a very light yellow and then turn brown. Unfortunately, the spots will never revert back to green.
South and west facing windows may experience more intense sunlight during the afternoon. Therefore, you may need to provide your Burle Marx additional protection in these positions.
