Nepeta ‘Purrsian Blue’ is covered with periwinkle-blue flowers from early summer through fall.  Plants are compact but have lots of flower power.  The foliage is green and scented with a spicy mint aroma.  Butterflies and hummingbirds are drawn to ‘Purrsian Blue’ for its nectar, while rabbits and deer avoid it because of its fragrance.  This catmint really pops in the perennial border or herb garden.
