The Rubber Plant, scientifically known as Ficus elastica, is a popular indoor plant known for its large, glossy, leathery leaves and sturdy, woody stems. These plants can grow quite tall, often reaching 6-10 feet indoors, and are prized for their air-purifying properties and ease of care. 

Here's a more detailed description:

• Leaves: The leaves are oblong to oval, typically dark green but can also be found in variegated varieties with cream, pink, or white markings. They can grow up to 12 inches long. 
• Stems: The stems are thick, woody, and upright, supporting the large leaves. 
• Growth: Rubber plants can grow quite tall indoors, sometimes reaching 6-10 feet or more, especially if they have enough space. They can also be pruned to maintain a more compact size. 
• Cultivation: Rubber plants are relatively easy to care for, making them a great choice for beginners. They thrive in bright, indirect light, moderate watering, and average room temperature. 
• Air Purification: Rubber plants are known for their ability to remove toxins from the air, such as formaldehyde and benzene. 
• Toxicity: The sap (latex) of rubber plants is toxic, so they are not pet-friendly.
