winter hardy canna

charles_ne(z4/5 E Nebraska)August 11, 2006

Hope this is the place to ask this. I had a canna survive the winter here in zone 4/5. Does this mean it has mutated and has become hardy?

Thank you for reporting this comment. Undo

well that depends, how cold was your winter. I have some species that survive my zone 8 winter, we had some temps in the teens for a little while.
