I grow and sell them every year. Although I still like the old-fashioned types I like the Knock Outs also. I started growing the "Drift Series" about four years ago, also long blooming and a product of Conard Pyle.
My absolutely favorite is the "Peach" rose because it tends to change colors, up to five(!) during its flowering period. It's not unusual to have each color at the same time once the flowering is in full force.
