You know my response. Dwarf Orinoco.
My tallest one was about 8' tall. That was to the top of the stalk where the leaves come out.
The actual height with the leaves sticking in the air was probably close to 15' tall. A total guess on my part.
The downfall with the orinocos is that they do have a lot of lower leaves and not sure if that is what you are looking for or if you want to be able to walk around under it.
I put in a ice cream banana spring of last year and so far its doing OK.
Not sure how tall it will get but its reported to get around 20' tall.
To young to tell how the fruiting goes.
