I have grown this particular bromeliad for over 5 years now and it is one of my favourite, both for flower and foliage. I have planted some of these out and as long as they are in a more sheltered spot or slightly closer to building frost should not kill the plant but some leaf damage is to be expected. I personally bring my larger plants in for winter, either inside the house or it will happily sit in a greenhouse/polytunnel for the colder season
