Common dandelion

<em>Taraxacum vulgare</em>, known as the common dandelion, is a perennial herbaceous plant in the family Asteraceae. This species is found in the United States, where it occupies a broad range of terrestrial habitats including lawns, meadows, roadsides, and disturbed urban and agricultural landscapes. <em>Taraxacum vulgare</em> is characterized by a basal rosette of irregularly lobed leaves, hollow flowering scapes, and bright yellow composite flower heads that develop into characteristic spherical seed clocks dispersed by wind. The species typically blooms from early spring through autumn and is capable of apomictic reproduction, allowing it to spread prolifically without cross-fertilization. It generally favors moist, nutrient-rich soils but tolerates a wide range of conditions. This dandelion is assessed as Least Concern and is considered a beneficial resource for early-season pollinators, including bees and butterflies. Its leaves and roots are also used in culinary and traditional medicinal preparations. Biological traits specific to <em>Taraxacum vulgare</em> as distinct from related aggregate dandelion taxa remain somewhat incompletely documented in the scientific literature.
