Exciting new Heuchera introductions! I am very fond of our California natives, H. maxima, and H. micrantha, but they have a tendency to get leaf fungus that is very unattractive, and seems to slowly kill them. I suspect perhaps a nutrient deficiency...does anyone have any experience with this problem, or rather success in dealilng with it? I have had it also on some of the older hybrid Heucheras as well.
Specifically relating to these new hybrids, how much shade can they tolerate?
Thanks for any help and info!
