Thank you, Bob.
I think I'll try and find heucheras with h. mircrantha in their lineage for my garden as I think they may have a better chance of survival in this climate.
It's interesting that the deer have not touched this plant, but ate the three heucheras I purchased down to the crown.
All three of them made it through the winter just fine. I think the high summer temps in an arid climate are harder on them than my winter temps, but clearly h. mircrantha can handle my summer temps just fine.
Smiles,
Lyn
