While I've seen bromeliads mentioned as generally safe on several lists, I have not (yet) seen any on the dangerous/poisonous/toxic lists. That said, it really depends on the particular species.
I was interested in including one at first, but after digging further, eliminated it due to temperature/humidity factors (one reason we stuck primarily to succulents). Bromeliads, like many other plants, can raise the humidity in the enclosure. They can also get HUGE, and outgrow the enclosure. Again, this may be species-dependent.
To be safe, I'd stick to those species specified in the many lists of BD-Safe plants. :wink:
