I do not like david austins that look like torn up used kleenex. The hybrid teas are a pretty flower to my eye but that is a useless plant for my garden conditions and funds to have to continue to replace them.
I can understand people want what they want and plant what they want. Gardening is fun.
FYI - Sunny knockout is fragrant it grows good in zone 6 I have seen it grown in a lot of garden center display gardens and a neighbor's yard. It is always in bloom and is a nice addition to his garden bed.
