I love this canna and have had it for several years. It gets 6+ feet tall and I love the leaves.
Dark Leaf Canna
Beautiful makshi!!!! If you ever feel like sending a rhizome or two I'd be happy to reciprocate with any number of things, Agapanthus, other Canna colors, Iris etc......
The bloom is more red. Thanks for the guess. Have any more guesses?
It looks like 'Red King Humbert'.

The leaves look the same but the flower doesn't to me. I will see if I can find another picture.
