This native classic is best known as a food of larval monarch butterflies (along with its cousins A. incarnata and A. tuberosa). Robust, yet beautiful with deep pink clusters of fragrant flowers in June and July followed by lovely pods of silky seeds in October.
'Sweet Kate' is an easy-to-grow perennial that produces a profusion of unusual deep-blue flowers from summer to fall. An eye-catching accent for the border, the vibrant golden-yellow foliage is the perfect foil for its bloom and a bright companion for purple-foliaged plants.
