a large, thick -walled clumper clumper growing in menlo park, california, zone 8 (lows 25 degrees F). fast growing. 8 years in ground from 15 gall pot.

here are 3 more photos, including one with cut-off old culms, showing the cross-section, and one with a new shoot. 2 id suggestions i've received so far are bambusa chungii and bambusa beecheyana. thanks in advance for any help.

I have no idea what it is but I sure would like to find out because I'd like to get some if it's a clumper. It's beautiful.

I don't have any idea what it is but if I find out I'll certainly be trying to get my hands on some.

Chungi is thin walled. not enough bloom for chungi.
Definately a clumper.
