Tillandsia plants grow by clinging to objects - whether it be a piece of driftwood, sand, or rock. Water them by misting them - these do not grow in soil. Offsets or pups can be mounted on their own once they are half the size of the Mother plant. Try these low maintenance plants today! A south, east or west window is a perfect location to display these. Prices start at $3.95 for small up to $9.50 for large plants.
