We are in love with this new and improved perennial with extra flower power. Cat’s Pajamas has a leg up on older Cat Mint selections in that it is shorter and more compact and it is earlier to bloom. Another improvement over previous varieties is its heavy production of indigo blue flowers from the soil to the stem tips instead of color only at the top of the plant. Cat Mints are loved by butterflies but avoided by rabbits and deer. Prune halfway back after the flowers fade to promote a second bloom.
