I guess that ARS has a "none of the above" category that it calls "modern shrubs." I remember from gardening in NJ that David Austin's introductions and other roses officially in the modern shrub category did much better than most HT roses where frost and blackspot were major threats. I was very pleased with Knock Out as a shrub, but a little less pleased with it as a rose.
I really appreciate knowing about Lady of Shalott and The Dark Lady, because I am always interested in increasing my stock of fragrant, vigorous roses. I found myself buying too many roses this year from VG almost in a single-handed effort to keep them open. Maybe next year I can add a few more DA roses to my stock.
