The Rubber Plant, Ficus elastica or Ficus robusta, is a hardy accommodating low maintenance houseplant, it also goes by Rubber Tree or Rubber Fig. The rubber plant (Ficus elastica) is a popular ornamental plant from the Ficus genus. Rubber Plants are not self supporting, the longer they grow the droopier they get. You can keep your rubber plant standing upright by using bamboo or dowels. I just use the leaves to hold it in place.
