I think you may be right Fred--they do look quite similar. And Cynthia, my UFO isn't large at all, must just look that way in the photo. Multiplies well here, but makes small fans.
Here's another seedling from a different year/different pollen
And another from the same group as earlier This one might actually be skinny enough to qualify as a spider.
It's so much fun to see what shows up from different crosses. I have finally started being good about keeping better records of the pollen parent cuz it's driving me nuts not knowing what did and didn't work with earlier crosses.....
