Areca palm

Dypsis lutescens, also known as areca palm, golden cane palm, yellow palm, or butterfly palm, is a species of flowering plant native to Madagascar.

Dypsis lutescens grows 20–39 feet in height. Multiple stems emerge from the base. The leaves are arched, 6 to 9 feet long, and pinnate, with 40-60 pairs of leaflets. One of several common names, "butterfly palm" refers to the leaves which curve upwards in multiple stems to create a butterfly look. It bears panicles of yellow flowers in summer. This plant acts as a supplier of fruit to some bird species which feed on it opportunistically.

It is grown as an ornamental plant in gardens in tropical and subtropical regions, and elsewhere indoors as a houseplant.

According to NASA and Dr. B. C. Wolverton, the areca palm filters xylene and toluene from the air. Wolverton also specifies that at 5 feet in height, the plant will transpire 1 liter of water per 24 hours, thereby making it an effective humidifier.
