Vigorous catmint with small, tubular, lavender-blue flowers held in clusters of upright stems from June to July & attractive, aromatic, light grey-green foliage. This tall perennial will form a dense mound that looks wonderful in the middle of a sunny border alongside other blue or silver-leaved plants. The flowers are highly attractive to bees, & of course, the foliage to cats, who will go mad for it. To prevent them from completely flattening it, insert several twiggy sticks into the centre of the plant.
