Common Nipplewort

<em>Lapsana communis</em>, the common nipplewort, is an annual or biennial flowering plant in the family Asteraceae (daisy family). The species is widely distributed across Europe, Asia, and North Africa, and has been introduced to North America and other temperate regions, making it one of the more broadly distributed members of its genus. <em>Lapsana communis</em> typically grows in disturbed habitats including roadsides, hedgerows, woodland margins, cultivated fields, and gardens, thriving in partial shade and fertile, moist soils. It produces small yellow composite flower heads and deeply lobed basal leaves. The common name references historical medicinal use — the plant was traditionally applied to treat nipple soreness and minor skin complaints, though these uses are not supported by modern pharmacological evidence. The species is currently assessed as Least Concern by the IUCN, reflecting its wide distribution and robust colonizing ability. Biological traits such as lifespan, body size, and diet remain poorly documented in standardized formal assessments for this plant species. <em>Lapsana communis</em> can behave as a weed in agricultural settings but also serves as a minor nectar and pollen source for generalist pollinators across its extensive range.
