Clump Tillandsias
Clumps are a collection of plants growing together in unison. After a tillandsia blooms, it begins to produce babies. These babies grow from out of the base of the plant. As the plants get bigger, the original plant which we call the "mother plant" withers away leaving a clumps of babies. You can separate these babies and grow them as singles, or leaves them together (forming a clump.)
