Bidens Aristosa

This plant is moderately resistant to damage from deer. Nectar from flowers attracts butterflies and bees. Its seeds are eaten by songbirds and ducks. Members of the genus Bidens support the following specialized bee: Dieunomia (Dieunomia) heteropoda.Strother, John L.; Weedon, Ronald R. (2006). "Bidens aristosa".

Bidens

Bidens aristosa (Tickseed Sunflower) is a fast-growing annual or biennial boasting a profusion of bright yellow daisies, up to 2 in. across (5 cm), held on long erect stalks. Blooming in mid to late summer, the large blossoms feature 6-8 bright yellow ray florets surrounding yellow disc flowers in their center. Rich in nectar, the flowers are a good pollen and nectar source for bees, butterflies, and other beneficial insects. They are carried above the bushy foliage of alternate, pinnately or bipinnately dissected leaves. The flowers give way to thin dry seeds that often have barbs. Songbirds, finches, sparrows and ducks feast on them. Tickseed Sunflower is suitable for growing in naturalized prairie or meadow plantings or along the edge of a woodland.

Bidens aristosa (Ozark Tickseed-Sunflower) is a midwestern species ('Michigan and Ohio southwestward'; Gray 1848; IL to IA, KS and CO south to TN, M, OK, and TX (Fernald 1950). It was first collected on the Atlantic seaboard from wool waste in Dracut, MA (1894) and North Berwick, ME (1897) (Canby 1900). Canby reported it (as Coreopsis involucrata) from 'reclaimed tide-water marshes at the junction of Christiana Creek with the Delaware River,' (Canby 1900). It now ranges on the Atlantic Coast from ME to NH to FL, and westward to CA (Godfrey and Wooten 1981); Natural Resources Conservation Service 1998).Bidens aristosa (Ozark Tickseed Sunflower) is apparently rare in the intertidal zone. However it is increasingly common in upland habitats (Brown and Brown 1984; Godfrey and Wooten 1981; Harvill et al. 1992). This species has been included on a list of invasive species for MD (Cooley 1993), and DE where it is 'dominating certain wetland types at the expense of indigenous species' (Delaware Natural Heritage Program 1999).
