I am from Iowa and wanted to get some cold hardy Bamboo started again.
I finally found 3' rhizome of Phylo Nuda available on Ebay.
Since I am in SC I knew that I was going to have to start it in a bucket. When it arrived I was impressed. It was a large strong section cut in to 2 pieces approx 20" long each. Each one had 2 - 3 strong canes ready to start. I put them in the bucket around the perimeter, they were so strong that could barely make them bend.
I planted them 2 weeks ago.
Good news! I noticed a pair of canes just peaking out yesterday and today they are both over an inch tall.
It will be interesting to see how big they get before we head back to Iowa in early June.
I have had Nuda in Iowa before an it seems to do well there.
