NCBG Seeds Bearded Beggarticks
This is one of the prettier and more drought tolerant Bidens spp. It blooms in marshes, meadows and bogs throughout North Carolina from August to October. Golden drifts of beggar’s ticks add late-summer color to the landscape. The name, beggar’s tick, refers to the seed shape. The achene has stiff awns that are barbed with two teeth-like structures which can easily latch onto humans or animals. This is a type of seed dispersal referred to as ‘hitchhiking’. The caterpillars of the butterfly Nathalis iole (Dainty Sulfur) are known to favor the foliage of Bidens spp. as a food source and the seeds are popular with Bobwhite and Purple and Goldfinches.
