The Story
Plant Bio
Nepeta tuberosa is a tuberous-rooted, herbaceous perennial with aromatic, gray-green foliage. It forms upright clumps and is highly attractive to bees and other pollinators. Distinguished by its tuberous roots which enable extreme drought tolerance. Produces dense spikes of two-lipped, violet-blue flowers. Unlike many other catmints, it is not known to be a strong cat attractant.
