It looks similar to Musafolia. How tall does it get?

Thanks for your reply.
That does seem very close. However, my plants don't have any red edging on the leaves, as yours seem to. However, given the sheer number of cultivars, I'll take it as "close enough is good enough" :)

As an addendum to the previous post, these cannas (in zone 5) are only about 3-4 feet tall, with the flowers rising above that.

I've read that there are 6 hybrids of Musafolia. Like all other cannas, they do best with lots of water and sun. I have seen musafolia planted in the shade in my area. The hight is only about 3 or 4 feet in deep shade but they still bloom. Mine only reached 6 feet in poor soil before I moved them. They are now over 7 feet.
