I can't recommend this company enough!
Nathan the owner, really cares about the plants he sells, as well as customer service. The tillandsias are top-notch quality, and prices are very reasonable, probably the best you can find. There are many tillandsias to choose from! They even have a collectors page, which is updated regularly for those hard to find species, hybrids, or cultivators. I've ordered three times now and have been VERY pleased.
