Dracocephalum parviflorum Nutt., American dragonhead, dracocéphale d’Amérique Annual to biennial, spreading by seeds; plants 1 to 3 feet (3 to 9 dm.) high; flowers irregular, blue to purple; most common in the mid-west; clover fields, gardens, native grassland, clearings, edges of woods, roadsides, and waste places; native to North America. Galeopsis tetrahit L., hemp-nettle, ortie royale Annual, spreading by seeds, 1 to 3 feet (3 to 9 dm.) high; flowers irregular, white to purple; throughout; gardens, pastures, barnyards, and waste places; introduced from Europe and Asia. Glechoma hederacea L., ground-ivy, lierre terrestre Perennial, spreading mainly by creeping stems that root at the nodes; flowering stems 3 to 10 inches ( 8 to 25 cm.) high; irregular flowers, purple-blue; throughout, but most common in the east; lawns, gardens, and waste places; introduced from Europe and Asia. Sometimes grown as a garden plant, but soon becomes a serious pest. Nepeta cataria L., catnip, herbe à chat Perennial, spreading by seeds; flowers creamy white or pinkish with pink spots; stems 1.5 to 6 feet (5 to 60 dm) heigh; throughout, but more common in the east, sometimes cultivated; gardens, pastures, hedgerows, fencerows, old fields, roadsides and disturbed areas; crushed foliage is strongly scented. Introduced from Eurasia. Prunella vulgaris L., heal-all, brunelle commune Perennial, semi-creeping herb, rooting at the nodes; flowers blue; throughout our area. Some populations are native whereas others are introduced. Often an aggressive weed in lawns. Also occurs in other grasslands, in waste ground, in open woods, and along roadsides. Stachys palustris L., marsh hedge-nettle, épiaire des champs A hexaploid perennial with subterranean stolons terminating in crisp, fusiform, whitish or whitish-yellow tubers. Stems 1 to 3 feet (3 to 9 dm.) high; flowers irregular. Introduced from Europe. Known to occur as early as August 1815 near Amherst, Maine. It is now locally common in moist habitats in southeastern Canada and in the northeastern United States. Marsh hedge-nettle tubers often penetrate potatoes growing in fields. This makes these potatoes virtually unsaleable. Text and photos of catnip by Stephen J. Darbyshire Click on a photo to view an enlarged image.
