Here is a NOID Tilandsia ($4.00 grocery store plant) that has been a nice, regular bloomer for me for several years, and one of the few where the bloom is good-sized (about 1 ½”). Just one at a time, however. Only when one dies, does a new one emerge. I know rhis is a common variety, but it never had an ID label, so I don't know exactly what it is.
