Areca Palms are great indoor houseplants. With their airy leaves, and tall growth habit, they are a perfect showstopper for any room. They add 6 to 10 inches (15-25 cm.) of growth per year until they reach a mature height of 6 or 7 feet (1.8-2.1 m.). Areca palm is one of the few palms that can tolerate trimming without serious harm, making it possible to keep mature plants indoors for their full lifespan of up to 10 years. A key factor in successfully growing areca palm trees indoors is providing just the right amount of light. They need bright, indirect light from a south- or west-facing window. The leaves turn yellowish-green in direct sunlight.
