Cheryl, I've never heard of problems like you're having with heurchs (that you posted on the other forum). I did look for information on heuchera diseases and here is some information I found:
"Plants that are too moist and shady may get some fungus problems during the summer. Moving them to a different site should solve this. The worst insect pest of the heuchera-tiarella group is the Black Vine Weevil, Otiorhynchus sulcatus. Larvae of this beetle bore in the roots and crowns of various plants, eventually causing the top of the plant to die. There is one generation of weevils per year, with the adults active in western Pennsylvania in June and the larvae causing most of their damage in the late summer and early fall. Inspecting wilted plants and killing the larvae is usually the only control needed in the garden. Introducing beneficial nematodes every couple of years is a good idea for control of weevils and other soil pests."
"Stem rot causes stem rotting and, under moist conditions, a white growth appears on infected parts. The disease is caused by Sclerotinia sclerotiorum and it may be controlled with drenches of Benomyl."
And here is an article on a variety of heuchera diseases:

If any of these sound like what is happening with yours, please let us know. I sure hope your able to diagnose and save them.
Bummer about your camera too. I stupidly dropped mine on the cement patio this morning and I can't believe I didn't wreck it. It's one tough little camera!
