About Pycnanthemum tenuifolium Schrad.
Pycnanthemum tenuifolium Schrad. is an herbaceous plant that grows wiry, green, branching stems between 0.6–0.9 metres (2–3 ft) tall. Like other mint species, its stems have a square cross-section. Its leaves are narrow, simple, arranged in opposite pairs, reaching up to 5 centimetres (2 in) long, and measuring less than 0.64 centimetres (0.25 in) wide. It produces white flowers that grow in dense, half-round heads, blooming from June through September during the summer. Unlike most species in the Pycnanthemum genus, its foliage has only a very faint mint fragrance. This species is native to central and eastern North America, with a range that extends from Texas in the west to Maine in the east, to Canada in the north, and Florida in the south. Its native habitats include dry open rocky woods, dry prairies, dry fields, roadsides, pine barrens, stream sides, and open wet thickets. In its ecosystem, Pycnanthemum tenuifolium attracts native bees, bumblebees, honey bees, and butterflies.
