The ball-shaped habit carries long, dark flower stems that hold indigo blue flowers. Unlike older varieties that only produce flowers at the top of the stems, this improved Catmint has blooms from the soil to the tips of the stems. Even when the flowers are past peak, the color of the rosy purple calyxes give your garden an additional splash of color. As an added bonus, the small, aromatic leaves keep deer and rabbits away. When Nepeta's stems are broken, they release an aroma into the air that tends to attract cats, thus its common name, Catmint.
