Steffen, any idea what a KR7346 looks like when older? Apparently, its similar to KR4558 and KR3032.steffen wrote:John, this is a very difficult question. To me several KRs look similar with respect to culm sheaths, culms, rhizome neck length and nodes: KR 5287, KR 5913, KR 6438, KR 6439, and KR 6791. They might all well be "grossas", on the other hand they are very different in size, uprightness and hardiness. Other KRs look very different and are most likely other species: KR 4175, KR 7613, KR 5177. KR 5177 with it's very short rhizome necks and smaller stature might match the description of macclureana.

It's from Vietnam, and flowered 4 years ago which is why mines only a seedling.
Glad I've got the 5287 - it looks fantastic!
