Does it kind of resemble like a miniature bamboo? And when you try to pick it will come apart right at the little joint? If so, we have that here in Michigan too only I think when I was a kid we called it snake grass or horse tail grass or something like that. In Michigan you can find it along beaches and near the water.
That's exactly what it looks like, and it breaks as you say. Found it growing along The Bayou. I was told Alligator grass, but when I looked it up, it wasn't anywhere close to my picture. I was also told, it only grew in Louisiana. I will let them know. Thank you so much.
