Rubber plants (ficus elastica) are retro chic defined. They're also very low maintenance, and have gorgeous rich dark green leaves. 

Light: They prefer bright, indirect light but can cope pretty well in lower light conditions.

Water: Water when the top 2cm of soil is light and dry and crumbly. 

Humidity: They're not particularly fussy, but wouldn't mind the odd misting. Wipe their leaves clean with a soft cloth every once in a while. 

Height and growth rate: They are moderate to fast growing plants (in the right conditions) and can get up to 2 metres tall. If you notice leaves dropping off, its possibly due to overwatering or insufficient light. 

Feed: A weak dose of liquid feed every 3-4 weeks in spring and summer will set it up nicely. 

Toxicity: Toxic if ingested so keep away from children and animals. Ficus leaf sap can also be an irritant. 

Origin: India and Indonesia.
