I am a Tropiflora groupie.
I have purchased tons of stuff from them and I visit them at least 3 times a month.
They have 4-5 houses full of tillies, and a football field size house of bromeliads. They also have a secret house that isn't open to the public but if you spend a little time with the staff, you might be able to sweet talk them into it.
Ask for Ray if you want to see/know about the cacti and succulents, and I think the walking bromeliad/orchid encyclopedia's name is Tony.
Ken, it's totally worth a visit if you can manage it. Gotta spend a lot of time there, it's not a showy nursery, things can be pretty mixed up and treasures hidden.
