Tick Seed Bidens aristosa

Phonetic Spelling
BI-denz a-ris-TOE-suh
Description

Long-Bracted Tickseed Sunflower is a herbaceous annual or biennial herb with a deep taproot that may grow 2-4 feet in height. It can be found in all parts of NC but is sparse in the mountains. The leaves have a sharply toothed margin, are opposite and pinnately compound (sometimes bi-pinnately compound). Large, yellow flowers mature in late summer and continue into early fall. The herb produces a thin dry seed (achene) that often has barbs.

It has been used mainly for landscape beautification but has a potential for use in cultivated garden situations, in naturalized prairie or meadow plantings, and along roadsides. It grows and flowers best in full sun, but is also adapted to partial shade. Plants are often found growing in the open shade along the edge of a woodland. It is adapted to most soil types, except for very sandy soils. Natural stands are generally found on moist sites such as in ditches, marshes, and wet meadows.
