A trouble-free plant whose leaves smell strongly of mint. The small, glaucous green leaves resemble those of Nepeta. Beginning in early summer, tiny, tubular, pale lavender-blue flowers are produced in profusion on upright spikes just above the foliage. Their sweet nectar attracts butterflies, hummingbirds, and bees. This plant makes a great filler in the border garden and can also be used as an edging.
