Bamboo Phyllostachys Viridis Robert Young
I bought two more bamboo from Bamboo Garden in Oregon to help screen out the new development behind our house. Good prices and fast delivery. Ned Jaquith is a very nice person to deal with, though no online ordering. These are not very hardy, only to zone 7 so I'm taking a chance by planting them in zone 6 but they'll go in sheltered places in the yard and hopefully with heavy mulching they will survive. I bought them mainly because of the beautifully colored stalks, a deep yellow to orange yellow. Here's a link that shows the color. And another site.
Here's a great bamboo cold hardiness chart from the Needmorebamboo site if you're thinking of planting some and don't know which variety to plant in your zone.
