"Flower Carpet Pink is a very, very nice rose and I am interested in getting another, but our local store doesn't seem to get this particular one in anymore. This rose has been the best rose anyone could ask for. Profuse flowering, little to no care for pests or disease...in fact, I think I have only had to spray it one time for whatever was causing holes in the leaves. I cut it down to 5 inches every fall and cover over the winter as here in SD we get really cold. It is the best rose ever."
