They may be either oval in shape, deeply-lobed or once-compound with 3-7 leaflets.

"This very common weed grows in a wide variety of habitats. Cobbler's pegs (Bidens pilosa) is well known as a weed of gardens, parks, crops, pastures, roadsides, disturbed sites and waste areas, but it also invades waterways, rainforest margins, open woodlands and coastal sites. For this reason it is also regarded as an environmental weed in New South Wales and Queensland., Cobbler's pegs (Bidens pilosa) is considered to be among the 200 most invasive plant species in south-eastern Queensland. Dense populations can out-compete native species, and are particularly troublesome in revegetation sites and on the exposed margins of bushland."
