(Billbergia nutans). I think it is only hardy in zone 10 & 11. You might grow it as a house plant though. Chrysothemis pulchella is 9-11, so looks like you have a couple of house plants. You could set them out in the summer if they are in pots but bring them in if it goes below 60°.
Hope this helps, good luck with your plants those are nice ones!
