Help Identify this Bamboo
My dad has a nice big bunch of this bamboo in his backyard and he's forgotten the name. Hopefully these pictures are enough to identify the plant, if not I can take more photos.
In July of this year, I dug up two of the culms and transplanted to my backyard. It was 98 degrees that day and I now realize that I probably put way too much stress on these plants and probably killed one of them.
Within 3 weeks of transplant, one of the culms turned brown and lost all of the leaves. I left it in the ground to see what would happen. The other plant looked good and had almost no leaf drop.
About 4 weeks ago, the healthy culm sent up a shoot. I was so happy! That shoot is now taller than the original plant!
Today, I dug up the brown dead looking plant. As I was inspecting the rhizome, I noticed what looked like some new growth, little 'buds'. I'm wondering if this rhizome will send up new shoots? Is that possible with no leafs?
Here are some pictures:
