Air Plant is the common name for members of the Tillandsia genus. Native to the West Indies, Mexico and much of Central America and South America.
They get their nutrients from the air and not soil. They absorb moisture and nutrients through their leaves, instead of through their roots. Rather than being stuck in soil, they attach themselves to things like trees, rocks, driftwood, and other structures, but they do not feed off of the host for survival.
They are air-purifying power plants. At night they photosynthesize. So while you are sleeping, they emit fresh oxygen into the air. They can help reduce stress and improve focus at home or work.
But do not mistake these beauties for just a decorative object and not treat them like a living thing. Air plants need several hours of light and love water just as much as the next plant.
