Re: heliconias
We get snow about every 20 years. We get several mild freezes though and that seems to be just enough cold to stunt the mature growth on the heliconia, which in spring, usually terminate. New growth then appears and the cycle starts over. Occasionally, with a mild winter, I'll have a few undamaged stalks of Rostrata, Pedro Ortiz, Scheideana and Latispatha Orange which will bloom. With a little protection, and lows no lower than 28, I can get all of the stalks to survive but it's a pain in the arse.
