    Should these plants be cut close to the ground when pruned?

      I cut mine right down to the ground in fall. It was its first year and didn't bloom which was really disappointing, but on top of that it developed powdery mildew. Am letting it come back this year and will treat it as soon as the tender new growth is up but might have to replace it with something else. Good luck with it!

        Diane: Thank you so much. I cut them down to the ground, and they are growing nicely out in in soon to be a desert California, if the rains we are getting today don't continue, this is our 4th year of drought and this looks like it may be the new normal out here.
        Again, thank you very much.
