I think that's how it's spelled. When I was in memphis, I saw this bamboo, that was 4 inches around, well, ok, maybe 3, but it was huge, l5 feet tall and he said it grew 3 feet a day, it was absolutely beautiful. He sells hostas, and other shade plants, his was growing in full shade, and I bought a 2 gallon pot , and he said in 3 years mine would be as big as his. It will be like christmas time when I see that day.
But I haven't been able to find any info on it, he called it pleoblastus bamboo.
WE planted it where we don't care if it takes over. He also told me it seems to like to grow in one direction, I had 2 different people tell me that that grow this bamboo, that it will grow in one direction, can't remember which direction, I guess if I see it's growing the wrong way I can dig it up and turn it around ha ha.
You are probably thinking of a different genus, as Pleioblastus species are almost all dinky 1'-3' tall bamboos... sounds like you are talking about Phyllostachys? Now THAT's a fast bamboo (or at least some are), and can grow up to 80' tall. All the Pleioblastus species I have grown are beautiful, often variegated and quite small (have to look down to see them, not up).
Well, he did call it pleoblastus and seemed sure of himself, I did a search once and a large bamboo came up that was a pleoblastus.
All I know is this stuff is abou t 4 inches around and it's at least l5 feet tall. and so beautiful. I can't wait for mine to be like this, and hope it doesn't take over LOL It could be the bamboo you mentioned, I guess I don't have to know, I know it was high dollar stuff. like 25.00 for a gallon pot.
