I had the opportunity to visit myself and actually got lost in the expansive shadehouses, as if that were a bad thing!
There's also a great selection of other rare plants too, like succulents and even a tropical rainforest dwelling blueberry!
The reason I'm just now sharing this link is because they now have a fully functional website. They used to sell mostly by mail order and their monthly "cargo report" which was fun, but not very accessible to newcomers like myself. Now you succulent nuts can browse through pages of sought after species and forms, and bromeliad crazyheads can peruse through the list of bromeliad genera and intergeneric hybrids you didn't even know existed!
Of course you can visit their shadehouses too, which struck me as a Disneyworld for tropical gardeners. They are open to the public and sell retail to individuals. Based outside of Sarasota at 3530 Tallevast Rd, there are over 7000 plants in their collection and they are all grown and propagated on site! I highly recommend reading the Our History page, as Dennis' success story is very inspiring to any gardener. They even send their rarities to botanical gardens and zoos around the world now!
Just to get you guys worked up about the selection, there are carnivorous plants, epiphytic cacti succulent ficus, rainforest ferns, terrestrial bromeliads, caudiciforms, ant plants, aloes, agaves, and best of all, many many more bromeliads!
One more thing, there's plenty of supplies, and some educational materials such as this excellent list of cold hardy bromeliads! Be sure to visit their fall festival from October 1st-3rd 2010 too!
