I saw many tillandsia, and many huge ones, in my travels in Central America and numerous Caribbean Islands. Of course most of these places were rain-forests, and it sure looked like the tillandsia were not slowing down any growth. But these were "wild" areas, not towns or cities. IF anyone has too many of them, send all you want to me. I would gladly pay postage for whatever you send. IF you know the proper name of what you send, that would be great, but I would take NOIDS without concern.
Just Tree-Mail me if you have some you want to get rid of.
