Thanks! It's nice to have a confirmation on that. This is a fairly new plant, with the first scape this year, so I wasn't sure if it was just the way the plant grew, or if it really was a prolif.
Donald, it is interesting that your prolif grew in the same place. I do think that there are two of them, but the other one is on the opposite side, and I couldn't get a good picture of it, thanks to the sun this morning. I'll try again tonight. The scape is still very green, since it still has a bloom or two to go. I'll keep an eye on it.
