ID needed on a clumping bamboo

[moriphen]

The mild winter of 2011-2012 as allowed my mysterious tissue cultured Fargesia sp. 'Scabrida' to come out unscathed and it has proceeded to throw up shoots which look nothing like the type plant at all. I'm beginning to doubt this bamboo is even a tissue culture and I was sold something else all together.

What I do know:

Plant is leaf hardy to around 10º F, Culm hardy to around 7º F









Photo is from last Nov 2011, But it shows the overall plant form.


Any help would be appreciated.

Here is a few pics of the Scabrida I killed. It didnt look like yours as far as I can tell:

Moriphen - That doesn't look like Fargesia scabrida to me.
Your plant does have interesting new culms though.

The culm sheaths look a lot like the photos I posted in recent thread about F apircirubens, but the aural cete (?) seem more pronounced.

Way too many leaves on individual branch. I'm not sure what it is, but it might not be Fargesia.

It does look like a nice bamboo all in all. Just unortunate people cant label their plants properly, or dont maliciously so they can make cash

Here is a photo (appologies for the poor quality) of a scabrida I bought recently.
Still in its pot, waiting to go in the ground.

The shoots are now 4 feet tall and are displaying pronounced "zig-zagging" at the nodes.

Still not a clue what clumping bamboo species this is.

[Gunnar_GG]

Yushania brevipaniculata?

Yushania brevipaniculata?

Just checked the branch nodes are not as complex.

[moriphen]

Another year has passed, and this oddball seems to be getting healthier. Still likes to shoot in June, with culms that zig-zag and branch nodes that favor 1 primary branch and 7 secondary branches. I think its in Fargesia or Borinda genus at this point

It's pretty whatever it is!

Could it be Yushania sp. 'Climbing' (Yunnan 95 5)?

I'd say not enough wax on the culm. It puzzles me, culm sheath seems to be way shorter than internode - not very borinda kind. Other than that, it looks almost identical to my Borinda fungosa that's growing in the shade.

Zig-zags occur when it starts branching, on the bottom of the culm, they are usually growing straight, higher up, they are more and more zig-zagged. Strong weeping habit of the culms that go almost half way down when first batch of leaves emerge. Like already mentioned, culm sheaths are long and only a small part of internode becomes visible before it branches out and tear the sheath off. Sheathes are extremely hairy. Culms are green when they emerge and there's quite a lot of waxy substance around the nodes. Leaves are delicate, a bit hairy and light green.

Anyone know the branching style of Yushania sp .(Yunnan 95 5)? Per: http://www.efloras.org/florataxon.aspx? ... _id=135232 "Branches often 1 at lower nodes, initially 5–7(–12) at middle nodes, 9–11(–45) at upper nodes, on promontory, erect or deflexed, subequal or central branch strongly dominant at lower nodes.". I will take another look tommorow to see if the branching is that varied, I will report back with what I find.

Can you take a picture and or count the branches? I have doubts its Borinda fungosa due to it being only cold hardy to 25º F.

I want to say it holds it leaves just like Borinda frigidorum, until i see file photo's of the new shoots which are far to waxy and of a different color. Finally, I checked my records and it was purchased from bamboosourcery.com in 2009, I will reach out to them over the weekend and see if they would be willing to lend a hand.

Going to photo dump what pictures I have, some have been posted before hopefully it will be helpful.

Yushania and Borinda are quite similar.
I'll take some photos later and show more detailed images.

Your photos show culms with sheath (much) shorter than internode. My bamboo, whatever it is, doesn't show much of it's internode until branches remove the sheath, because it's usually longer than the internode. I think that culm sheath may be the main difference amongst Yushania and Borinda genus.

Some photos can be found here: http://www.bambooweb.info/bb/viewtopic. ... 33&p=57910 or here http://cold-hardy.com/?p=111

The length of culm sheathes makes the new shoot look a bit exotic - hollow inside and ... see for your self.
