I'm not familiar with the growth pattern of the O.A. This is the first new growth since I've had it, and it looks very different from the original plant.

If somone who is familiar with this beautiful bamboo, could please examine the new tall culm along with the new leaves and compare them with the shorter, older growth, I'd appreciate your comments. I'm concerned that a different type of bamboo may have been part of this clump and if so, I'd like to remove it immediately. I know each seasonal culm will be wider and taller than last year's growth, but this is excessively wider and taller!

Of course, if the new growth is actually part of the O.A. I'm delighted. The culm is so very much thicker than the original clump, and the leaves are certainly not as slender.

I did not buy the O.A., but received it as a gift so I'm not sure if another bamboo spread into the original clump from my friends garden.

Thanks. Hope someone can reassure me that its actually all Otatea Acuminata!
