I think perhaps you went on your rant a little too long there! Because some plants such as Aucuba and Lonicera nitida have been overused as amenity planting, doesn't make them bad plants...quite the reverse in my opinion! They are plants that work well in many conditions and are extremely successful in what they do, that it is OUR fault, the INDUSTRY'S fault that you now despise them. Heuchera caramel is one of THE most stunning ground cover plants I've ever come across, especially when combined with other deep violet varieties to exaggerate the gold and bronze foliage. I do agree with your last paragraph though, taste goes around with fashion...laburnum, forsythia and kerria were favourites of the gardeners of old, but now many also despise these plants...personally I find laburnum belongs in victorian settings such as terraced houses, but they would never be exempt from contemporary plans I might compose simply because the popular belief is that you shouldn't!
Opinion is opinion, I do not contest that, but one man's trash is another man's treasure!
