Hi Steve, I hope you're doing well. Yeah, that's the one. The only way I'd plant it in the ground is if I end up with too much to keep in the pot. I had another shoot come up about a month ago but it looks like it can handle being in the 5 gallon pot for a while longer.
As for the others, I'll probably plant pretty much whatever Bryan wants me to plant (he'll donate the rhizomes and I'll donate the space and time.
I'm a toasty zone 9, only got done to 30F this year!
I'm hoping to build a large shade structure (30' x 50', approximate) to be able to shade some plants in the hot summer and to provide frost protection in the winter. The little structure over my lychee seemed to work out well as even some young tender growth made it okay this winter (we had about 30 days of frost).
I hope your Ae Ae is recovering!
Harvey
