Identify & Control: Scentless Chamomile (Tripleurospermum inodorum)

As a summer annual, winter annual, or short-lived perennial, Scentless Chamomile is a noxious weed often mistaken for its non-toxic look-alike, Ox-eye Daisy. Both have white petals and yellow centres, but the leaves of the Scentless Chamomile are distinctly, finely divided into short, carrot-like segments. Scentless Chamomile reproduces only via its seeds, yet one square metre of this weed can produce up to one million seeds which float on water, a main path of distribution. It is typically found in disturbed, moist areas like roadsides, utility rights of way, drainage ditches, shelterbelts and waste areas.¹
