I have no idea where to put this but since I am going to use it in a container I am trying here first....
I got it last year from my local nursery as a gift throw in the bag. They had a mini garden class and left over they throw it in customer bags as left over from classes. So I know it is some kind of a mini plant.
When I saw the stem coming up I thought a usually stick thing that normal size grass grows. But it bloomed today. It is hardy because I left it in this pot last winter. It is 3" wide and about 1" high. Of course higher if I added the flower but the green/white grass part is small.
