Cleopatra has no green?
I saved a one gallon sized division of Cleopatra in my greenhouse over the winter.
It is now 5' tall with multiple stems and gorgeous but has no green at all.
I know it is Cleopatra, the parent plant I divided had both green and maroon leaves and red and yellow flowers. Unfortunately, it was too big to fit in the greenhouse and died.
I did not have any solid maroon cannas for this to have been mislabeled.
