This is the Musa Basjoo (hardy non-fruiting banana plant) that I posted about a lot last year. I don't know why it didn't make my blog in 2007 yet, I didn't lose interest in it or anything. I guess I just never got around to it.
In any event, it's doing great and getting pretty tall even though it's in a pot. To give you an idea of it's size, the pot in the picture has a 24" diameter and the tip of the highest leaf is about 10 feet up.
The added bonus was that there were two pups that grew in the pot with it last year. They got to be about 3 feet each by the end of the season. So I brought all three into my garage to overwinter sometime around late September. It's hardy and would probably live through a New Jersey winter with some heavy mulch and maybe some plastic to keep it dry, but I like to play it safe.
I planted the other two in the ground near my pool to give it a nice tropical look. Each on is about 5 feet tall now.
And you can see that I have another pup growing in the pot again. These things are awesome!
