Hi scott. If you dig it you can have it. I have buddha belly and I believe golden. You need to dig it yourself as a bonus If you dig most of it up we can give you a few other divisions of other types also.

Oldhamii is good for screening since it grows very upright and doesn't lean outward. Others will take up more space. Oldhamii will probably grow closer to 50 feet tall in your area. There are dozens of varieties that will do well and grow tall in your area. Kt

The poles aren't as strong as you might think (native cane). The plants are very sensitive to the occasional droughts. I had a good stand behind my back yard in a forest and during the drought they died off . Later I found it growing in a low spot that normally floods. Ground water is going to be the key issue and rain runoff ditches are probably the best site for establishing a stand. Still, they spread underground and re-establish where there is adequate and continuous moisture so I have no idea how you would contain them. I don't find them attractive at all. A summertime short visual barrier if there's enough moisture but the rest of the year and in dry periods they do look ratty and the dead,dying leaves do persist. Are you trying to hide a view? As I mentioned, they aren't a permanent barrier. In the riverine (drainage/creek overflow) forest they would pop up in a different location every few years.

I'd be interested in knowing what sources you researched, as IME most will provide almost identical information :-)) There's several different species of clumping bamboo but the Fargesias tend to be used very widely as they are commonly available, tend to be some of the most cold hardy and come in various species and cultivars that offer different mature heights and habits. 1. No, they are not invasive and you do not need a root barrier to contain. That's why they are considered 'clumping' rather than 'running' bamboos. They do not have the very aggressive, monopodial rhizomes that can produce culms at great distances from the mother plant. Rather, they have a sympodial rooting system, producing dense clusters of new growth, with a slowly increasing overall clump size. This is the same way many other types of popular ornamental grasses grow, like Panicum or Miscanthus. And bamboos are just tall growing, woody based ornamental grasses :-) 2. How many you would need to fill that area depends on the specific selection, what kind of growing conditions you can offer, how big your plant budget is and how long you are prepared to wait for full privacy screening. It won't be immediate......even running bamboos take a few seasons to fill in. 3. Height again will depend on selection. Once established, each new culm will achieve a mature height in a single growing season. So yes, it grows fast. 4 &5. It is both deer resistant and evergreen. The American Bamboo Society is an excellent resource. And of the commercial sites, Bamboo Gardens provides very good information on the types of bamboos and preferred growing conditions as well as answering a whole raft of bamboo growing issues. Both of these are my go-to sources for info on bamboo.
