From Flora of Indiana (1940) by Charles C. Deam
Prefers a moist or dry sandy soil and is frequent to common in all parts of the state. Too frequent in waste places about dwellings, truck gardens, pastures, and open woodland. At our home we regard it as an obnoxious weed, and even by persistent efforts can not entirely eradicate it.

Duration: Perennial Nativity: Non-Native Lifeform: Forb/Herb General: Aromatic perennial with sparsely pubescent stems 30-150 cm tall. Leaves: Blades 1-3.5 mm wide, 1.5-4.5 mm long, deltoid and stipulate, on petioles 1-4 cm long, the base subcordate and the margins crenate with veins that terminate between the marginal teeth, blades sessile near the top of plant. Flowers: Verticillate cyme of tightly clustered verticils at branch tips that form a large leafy panicle, the flowers on pedicels 0.5-2.5 cm long, urceolate calyx, persistent, about 4 mm long, pubescent with short glandular hairs, the lobes acuminate, with magenta veins, the corolla white to pink, the lower lip crenate, with magenta spots, stamens with white filaments and purple anthers, magenta pistil. Fruits: Nutlets, oblong, glabrous mm long, 1 mm wide, longitudinally concave toward center. Ecology: Found in disturbed sites, roadsides, and along stream banks from 4,000-7,000 ft (1219-2234 m); flowers May-September. Notes: Distinctive with its crenate margined leaf blades, the deltoid shape is key along with the tightly clustered verticils of flowers. Ethnobotany: Used against intestinal worms, as a cold remedy, for coughs, for fevers, for boils and swellings, as a sedative to soothe infants, for headaches, against diarrhea, as a sleeping aid, blood purifier, for rheumatism, and the leaves were made into a tea. Etymology: Nepeta is the Latin name for catnip, while cataria means pertaining to cats. Synonyms: None Editor: SBuckley, 2010
