Bamboo in WA. State
We are looking for a very hardy variety which will do well in zone 4, the S W corridor between Seattle, WA. and Portland, OR.
We have a slight hill side that we would like to used bamboo as a barrier/windbreak, so we need a variety that will spread easily and the height of the plant is not a problem.
One question we do have is the depth of the root system. We have about 3' to 4' feet of soil before the roots will grow into our drain field which would not be a good thing.
Thank you in advance for any help you can offer!
