verge d'or rugueuse

<em>Solidago rugosa</em>, the wrinkleleaf goldenrod or common wrinkle-leaved goldenrod, is a perennial herbaceous plant in the family Asteraceae. It is native to eastern North America, distributed from Newfoundland and Quebec south through the eastern United States to Florida and Texas, where it grows in a variety of moist to wet habitats including streambanks, floodplain forests, wet meadows, bogs, and disturbed areas. The species is easily recognized by its distinctive wrinkled or rugose leaf surface, which gives the plant its common and scientific names. Stems typically reach 60–200 cm in height and bear arching, one-sided clusters of small yellow flower heads that bloom from August through October, providing late-season nectar for pollinators. Biological traits such as precise average lifespan and detailed morphological measurements remain poorly documented at the population level. <em>Solidago rugosa</em> is a vigorous colonizer of disturbed and semi-natural habitats and is sometimes considered aggressive in managed landscapes. It plays an important role in supporting native bees, beetles, and butterflies. The species has not been formally evaluated for conservation status by the IUCN and is considered broadly common across its native range.
