From Wikipedia, the free encyclopedia
Of the alien British Conyza species, this is the second most abundant (after C. canadensis) and is common on waste ground, railways and disturbed ground in London and south east England. It is known by the floral bracts which are distinctly hairy (in contrast to C. canadensis and C. bilbaoana) and by the leaf margin hairs (which are bent forward rather than spreading at right angles as in C. canadensis). It flowers in August and September and has dirty white or rust coloured pappus hairs. Although an abundant alien, it is not invasive in any natural or semi-natural habitats.
