1. If possible, I would like to find some sort of bamboo that will not be invasive and which grows enough to be harvested for multiple tall garden supports on a yearly basis. I have relied on Freecycle and Craigslist in the past, but haven't seen any offers in a couple of years. Generally, the cut bamboo seems to last only a season and is too deteriorated to re-use, so I am thinking along the lines of growing my own if these criteria can be met. South central PA, zone 6.
2. Which bamboos could I grow in a 3'x3'x2' container on a sheltered north facing open patio (one story wings to E and W, 2 story to S) for a wind-catching musical accent planting? If not hardy to a zone, can they overwinter in a cellar?
