If your talking of the coop I think you are, I packed your heuchs and they were pewter moon.
I personaly opened the box from the grower and sorted. I have 4 of the pewter moon and they too have the ring of fire. I wonder if it's a grower mix up... or we all have a new cultivar "pewter fired up" lol
At the moment, I don't remember what I ordered from that co-op - I think I got a substitute for one of them, but I'm really happy with them. One of them started developing the ring you're talking about in August and I thought it was a disease at first, so I'm glad to see this thread. I have a few pictures to post. This one has the ring showing:
In July I noticed one of the plant's crown was really loose and the plant was flopping over. I think a grub was snacking on it, so I planted the pieces and wound up with three plants. Two of them are the small ones in the top of this pic.
The plant on the lower left is the same type as the previous picture (pretty sure, anyway...), but this one didn't get the ring. If anyone has any ideas which Heucheras these are please let me know.
You got me there... mine came with some tags, but I'm not home right now to check. And if I remember right, the tags were for the light colored one, which I think is 'Snow Angel', which is not the one showing the ring.
what co-op did you get your Heuchera from ?
mine came from the co-op by summerkid from casa flora http://www.casaflora.com/heuchera1.htm
the only Heuchera available for that co-op were
Beauty of Color
Crimson Curls (has 25-cent patent fee in addition) http://davesgarden.com/community/forums/t/686912/
which as you can see contain none of the names you have ???
but your plants do resemble some of them :-)
Different summerkid co-op, I guess. The "Helleborus plus" co-op from Northwest Bulb. The only Heuchera in that co-op were Palace Purple, Plum Pudding, and Silver Scrolls.
I guess I forgot summerkid had a few co-ops going at one time, which is probably why they were late. Sorry for the confusion, I remember your name from the one I was in too. So now I'll check mine against the plants you named, maybe I'll figure this out yet!
