I read another article where he responded to objections that they didn't look like exhibition-winning roses. Basically he said "yeah, they aren't exhibition roses. They're shrub roses, landscape roses."
He also likes the fancier roses, and some of his non-KO introductions lean more that way, but the KO line is intended to be what it is - a low-maintenance landscape rose.
Since he got the "fully double" bloom form in the newer cherry double KO variety RADtko, I've withdrawn my complaint that the blooms don't look like my favorite rose forms. Now, they pretty much do.
