The Rubber Plant, or Ficus elastica, is a popular, low-maintenance houseplant known for its large, glossy, dark green leaves and potential to grow into a tree-like shape indoors. It's an excellent air purifier, removing toxins and releasing oxygen, and requires bright, indirect light and moderate watering when the soil is nearly dry. The plant's latex sap was historically used to produce rubber, and it can reach heights of 6-10 feet or more when grown indoors.
