    Lovely, lovely, lovely is one thing I really want to say to describe this gem of a rose. Small full blooms cover a smallish shrub here in my garden. I don't know how to describe the unusual color. All I know is that I was instantly stopped in my tracks as soon as I saw one in bloom, and I had to buy one. I do spray Margo Koster with a systemic fungicide here in my humid Long Island, NY garden because almost all of my roses need spraying to remain disease free.
