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.
Soft, fragrant, gray-green foliage with sprays of large, distinct bluish purple flowers from April to October. Compact, prolific and beautiful! Named for English garden Walker's Low.
