Thank you for your response.
I think it is the dry heat that is harder on the heucheras with the villosa species in their lineage.
h. villosa is native to the southeast US ... a more humid climate. I think I have to find plants with
h. mircrantha in their lineage because it is found in more arid climtes. See
The thread "Is this H. micrantha ?" in
Heucheras forum
I live in the lower end of the Klamath mountains at the 2400ft elevation. I am certain that the folks at the higher elevations in the Trinity Alps do experience soil freezing in the winter.
I had planned to move my
h. mircrantha plants this fall, but now, I think I'll wait until spring. My neighbor cut down the tree that was giving them shade, so I am shading those plants, too. Oh, and for the first time in 10 years the deer ate them down to the crowns. I am trying to get them back.
It's always something.
Smiles,
Lyn
