This is one of the fattest, bulbous Tillandsia apart from T. bulbosa. It grows to a girth of about the size of a softball. Some may grow larger. Somewhat a xeric grower that need plentiful of sunlight to have those fuzzy looking and ofcourse the 'tennis ball' look!
It's native to the state of Chiapas, Mexico at about 700m altitude where it grows at granite gorges.
