Ficus elastica, also known as the rubber tree, belongs to the mulberry family and originally comes from India and Indonesia. There, the rubber tree can grow up to 25 meters tall. In Germany, it was particularly popular as a houseplant in the 1980s and has been making a comeback in recent years. The "Robusta" variety is a very low-maintenance and robust species, which, with its leathery, dark green leaves, is especially well-suited as a solitary plant in an office or living room.
