Thank you, Zuzu. My Sweet Alyssum only lasted one season. Maybe it's the cold. I don't really know. I've stepped on the sedum I planted under one rose, but when I was pruning the rose I stepped on it too much ... ooops. I am planting the sedums in the rock borders surrounding the rose beds instead of in the rose beds. I do have Iberis in the garden, but not in the rose beds.
I discovered Mrs. J had planted some dichondra in her rose bed and I can step on that just fine. I don't mind stomping on the dang violets, but they smother the feeder roots of roses.
Now there is that weed that I am thinking of reclassifying as a ground cover. Maybe I should take a photo and see if I can get some help identifying it.
Smiles,
Lyn
