Denverian

Here in Denver, I'm at zone 6a, and have had little success with the basjoos. I could only get them to come back from the ground, and then had very little growth (maybe up to 3' over the summer)

Last year I found a good deal and a rather large red banana (I don't know what the specific variety is) and it got to around 10' last year. We bought a small greenhouse last year, so I dug it up (these things have a much wider trunk, so it was rather heavy!), put it in a big pot, and it lived in the greenhouse. Now, after moving it back outside last month, it's already at least as big as the end of last summer! My only concern now is that it may be too big to dig up this coming fall. I may have to chop it off to save it.

Oddly, I missed a few elephant ear bulbs when I dug them out last fall and some came back on their own. I didn't mulch them or anything. I had no clue those were that hardy!
