Great plant. I got it from my grandmother many years ago. It gets real tall and the hummingbirds love it. I do have some in a container they donot get as tall as the ones in the ground.

I have been growing cannas for years in zone 5. They are planted right next to the house, on the south side. I don't dig them up or anything; they just keep on blooming each year!

I have this canna growing in a container. I love the small size (maybe under 2ft.) and the hummingbirds love it too...seems to be one of the first flowers they visit in the morning.

aka Canna compacta. Very attractive to hummingbirds. Hardier than many cannas; will possibly survive zone 6 winter in the ground (mulching and protection from wind will help).
