After a horrible spring and hot dry summer ..fall has been long, wet, and warm.
Many these clumps started out just one rhizome spring 2002.
Yes, you can grow cannas colder climates (o:
Harvesting Cannas .. sw Pennsylvania, USA
Oh my gosh. From one little rhizome. That is amazing. Mine certainly did not do that well. What zone are you in? It doesn't say up above.
hmm.. Brugie,
Did not realize no zone for me. Will have to check that out.
I am 5 1/2-6. At a higher elevetion than most here.
But even though high, I think more the 6 zone (microclimate).
My cannas were dug some time ago. They probably would have been okay in the ground, but the tops had frosted and by now they would have frozen.
