My huecheras have some sun scorch, but all of them have made it through the worst heat and are putting on new leaves. I plan to divide two of them this fall instead of waiting until spring because there are so many other things to do in spring. I think they will make it.
I don't have a lot of roses blooming in the garden because of the heat, but temps are starting to drop and that should make a difference quickly.
Smiles,
Lyn
