would it be possible for canna to survive in my area?
usually anything not viable in my area, i just leave and let it decompose over winter. i don't have room for overwinter storage anyway... so, come spring time i just use my judgement to clean things out as i go along.
as i was going through an area i had canna in last yr, i found some that looked like they might have made it over winter... not shriveld or mushy... maybe i need to get some fresh canna to remember how they look...
this winter was predominantly mild except for a few cold snaps not lasting more than a week... the canna were within 15 ft from my home and there's a fence that caught leaf debris that could have hleped insulate it.
anyone have any thoughts on this? thanks in advance :)
