Wow, what a gorgeous plant! But, I think it may be a Travelers Palm. They sometimes get confused with Strelitzia but get quite a bit larger. While Strelitzia grows to heights to 30' the Traveler's Palm can reach heights of 60'.
Traveler's Palm, Ravenala madagascariensis:

If I'm wrong please forgive me, but if your photo is indeed the Travelers Palm I hope you will submit a proposal to move your great picture to the entry for Ravenala:
