Noteworthy Characteristics

A fast-growing, strong-stemmed perennial in the mint family which grows 4-6' tall and produces whorls of tiny, greenish-yellow flowers closely packed into 5" terminal spikes on stiff, square stems. Toothed, arrowhead-shaped leaves are up to 5" long, but lack the fragrance common to many mint family members. Tolerant of summer heat and humidity. Long, late summer bloom, sometimes extending to first frost. Attractive to bees and butterflies. Species name is in reference to the similarity in appearance of this plant to catnip or catmint (Nepeta). A fairly common Missouri native plant that typically occurs in moist, rich, open woodland areas, thickets and woodland borders throughout the State.

Problems

No serious pest or disease problems.
