Bidens tripartita, commonly known as Three-lobe Beggarticks, is an annual herb native to a wide range of habitats including moist areas, riverbanks, and lakesides across much of Eurasia, North Africa, and North America. It has also naturalized in Australia and some Pacific Islands. This species typically grows to a height of 20-60 cm (8-24 inches) with rigid stems and fibrous roots. The leaves are opposite, lanceolate, and deeply lobed. From late summer to fall, it produces small, yellow, discoid flower heads that lack the showy ray flowers typical of many daisy family members. The flowers are not particularly showy but are attractive to pollinators.

Three-lobe Beggarticks is valued for its adaptability to wet conditions and is often used in rain gardens and for erosion control. It thrives in full sun to part shade and prefers moist to wet soils with good drainage. While it is not known for significant diseases or pests, it can become weedy and potentially invasive outside its native range due to its prolific seed production. Gardeners should be cautious and check local regulations before planting, as it may be considered invasive in some areas.CC BY-SA 4.0
