Do you know if they have any air plants or terrariums ?

Call them

I bought air plants there last year, and saw some when I was there in May. Not a huge selection, but a few varieties to choose from. Have not seen terrariums though.

I have not seen any airplants or terrariums there and I go almost weekly.

I don't think so.

I don't recall seeing any there. You could give them a call though, they're very nice.
