What is a Tilly?
A Tilly is a pet air plant. “Air plant” is the common name for plants in the genus Tillandsias L. Air plants are also lovingly and commonly referred to as Tillies by their human adoptive parents. Most are epiphytes and grow on trees, rocks, logs or other structures without causing any harm or taking nutrients. Pet air plants get moisture & nutrients from the air and absorb them through their leaves instead of roots.
