As noted by NYT's Theresa Burns, (sorry, print edition only) "in a world replete with false advertising, darned if many of them {butterfly bushes} aren't covered in butterflies this week."
The deep purple flower is likely "Dark Knight", i.e., one of my "Peacock"'s is mislabelled. This might be a problem, because "Dark Knight" grows to two-three times the size of "Peacock".
