Bidens pilosa is naturally found in Europe growing in most well drained fertile moist to wet light soils in an open sunny position and is frost and drought tender. 

Cobblers Peg is a hardy persistent weed that is normally found in disturbed soils along roadsides or invades dunes in coastal areas. It is not normally cultivated in gardens as it spreads rapidly and is difficult to eradicate. It is normally controlled by physical removal of the plant and roots but care has to be taken not to spread the seeds as they attach to most clothing. Chemical control may be used but will require follow up applications as seedlings appear. ID 808
