Deep royal blue-violet panicles on green (by butterfly bush standards anyway) foliage. This is a blooming machine, and went from a foot high to 4ft high in its first year in the ground. The blooms show up even from 100ft away. The less-silvery leaf color makes the blooms pop more than ones like 'True Blue' where the blooms blend into the foliage from a distance. I've grown several butterfly bushes, but this one stands out as perhaps my favorite.
