I noticed that when I looked at the few photos posted on the internet. Since there is room my approach will be to grow all of them out and see if one stands out. That one will get saved as cuttings next fall while the parent will be left in the ground in the hope it might prove hardy. Generally it is probably better to go through a breeder like you for selections of a plant like this since it is your specialty, but the seeds were a gift, and seeing what develops adds a little drama to the season.
