These increasingly popular plants can grow and thrive without soil by getting all their moisture, light, and nutrients through their leaves. There are more than 500 types of air plants (Tillandsia sp.) which are native to southern United States, Mexico, Central America, and South America.
As their name suggests, constant air circulation is the key to keeping these plants happy. Air plants need some moisture. If the leaves start to curl under, the plant is likely gasping for water. You can submerge the plant in water and gently shake off any excess water about once a week. Light misting is also effective a few times a week depending on the season. These plants love warm temperatures but need protection from full sun.
Air plants are extremely versatile and can be displayed and enjoyed by mounting them on decorative surfaces such as shells, rocks, driftwood, or in glass.
