Tillandsia duratii (dure-AH-tee) is one of, if not, the most amazing Tillys. Its shape is incredible, it is the hardiest species, and it is the most genetically unique. My friend, Dr. Mark Dimmitt, has told me that for him, it is the only species that will grow outside all year in Tucson, AZ. It produces more fragrant flowers for a longer period of time than any other species. What a great Tillandsia!
