I am going to have to hunt up the name of the bamboo. So far, so good. There is some winter dieback with it. But two clumps border an asphalt driveway so stay warmer than the other two clumps on the opposite side of the yard. They are not growing as fast as the driveway Boo. Plus a lot of competition from old tree roots over there.
What is the height of the Phyllostachys nigra?
I overwinter zone 7 also and some things a bit higher. They argue all the time about whether our area is 6b or 7a. Whatever ... I overwinter canna, musa basjoo and Colocasia with about 6" of straw mulch on top.
Got this canna shot in the early morning dew today.
This is our second year here and second year for the new EE and shade bed. I only lost one big EE this year. It made it through the winter just fine and then rotted when the seasonal creek behind kept rising up into the yard during a very wet Spring.
