Life Cycle

It is a short-lived perennial or sometimes annual.

Stems

Its stems below the flower heads are smooth and hairless, and the whole plant is virtually without odour.

Flowers and Fruit

Large yellow-centered flower heads with white ray florets.

Habitat

It occurs sporadically in Ontario in waste places and roadsides, but is becoming a significant weed in pastures and some cultivated fields.

Distinguishing Features

Scentless chamomile closely resembling Stinking mayweed with its large yellow-centered flower heads with white ray florets, but it is usually taller (up to 75 cm, 30 in.) and more branched. Its stems below the flower heads are smooth and hairless, and the whole plant is virtually without odour.

Often Mistaken For

Very similar to both Pineappleweed and Stinking mayweed.
