I had it for several years in Ohio and it was just as Vickie described. The downfall for me was the height, but I did like the blunt sepals.
It is also one of those plants that begins to open the day or so before, and those blooms appear to be deformed until they fully open...
kind of like a butterfly that has just emerged from it's cocoon. The down side of that is that it tends to be spotty sometimes.
I don't recall that I ever got any pods to mature on it, but that was several years ago. I just got it again this year, which says a lot.
The evergreen plant was also an issue for me at the time, and I think it might perform better further south, but it did fairly well here.
Unlike a lot of evergreen plants, this one did increase well. The low bud count was also an issue. There were times when a scape
might only have 4 buds, and sometimes 8. The green throat is the part that I wanted.
