I'm in North Florida and both came thru for me this winter. It was a mild winter of course, but I mulched well. I have not had blooms yet but if I'm going to this should be the year. Good luck!

I'd expect them to not survive but it depends on where in Al. you live. If the ground freezes where you live, I'd not expect it to survive.
Both are rootable from stem cuttings.

p.s. my grandmother used to grow Hedychium coronarium in Montgomery and covered with with pine straw in winter.

Jeff, I can't speak to either of the kinds you listed, but I can say that Hedychium coronarium survives in zone 7 in B'ham w/o any extra assistance whatsoever from my next-door neighbor. They have 8-ft stalks of weeds growing so you know they don't mulch. They people have lived there for 7 or maybe 8 yrs so I can't imagine that all of those winters have been incredibly mild....
