I have trouble keeping Heuchera alive in not so bad winter so I was not surprised that I lost most of mine. It is not a big deal because I know they are iffy at best in my garden so I only buy them if they are 5.00 or less.
My rhododendron and my azaleas would have been fine but the deer were so hungry because of the bad winter they decided they had to eat what ever was available. Rhody is low on their list of eating but they had to be very hungry. It was funny they ate the white one but did not bother the purple.
This was last yr. This year I did not get any white blooms at all. There were only leafless stems.
By the way Heucheras are 2.99 at Santa Rosa. They have some of the ones I lost.
