This native perennial has beautiful showy lavender flowers that last from summer through fall providing a gorgeous color when most flowers are gone. It is a groundcover selection of the species that spreads rapidly which makes it a great option for borders or containers or as a lawn substitute. It will bear light traffic. This plant grows from rhizomes  so some form of edging to contain its eventual spread and keep it in bounds should be considered when planting. It attracts both butterflies and birds which make it a great choice for both butterfly and bird gardens especially since the flowers bloom in summer and fall when most plants have stopped flowering.
