Shoots from culm nodes on Semiarundinaria

Post by Alan_L »

I did some work on my Semiarundinaria fastuosa 'Viridis' last weekend, and found something really interesting on one of the culms: it had produced two new shoots from its nodes!

Is this typical for Semiarundinaria? I haven't dug around this plant much before, so this was a surprise. Gives me hope that when I finally dig out that variegated Semi. okuboi culm it could produce more variegated culms.

I'm not sure I see what you are saying? To me it looks like all the growth is coming from different rhizome buds no?

In the top photo, the rhizome is the darker one running almost vertical (in the photo). You can see the one culm attached to it. In the bottom photo (which is a little cut off) the existing culm is in the center and you can just see the other two culms coming from it. You can't see the rhizome in that third photo, except in the background.

Alan I see what you are saying, perhaps it's normal for a semiarundinaria. I just don't want to dig mine up to find out :D
The bottom of the culm being not exposed to Sun and retaining two viable buds has make two new culms.

I dug some wayward Semiarundinaria okuboi rhizomes recently, and saw the same thing: there are buds on the lowest nodes of the culms. Presumably these can turn into rhizomes or shoots? I've seen them turn into culms, but haven't seen evidence of rhizomes yet. Anybody else?

So I'm thinking that this is definitely a trait of Semiarundinaria.
