Scentless Chamomile is an annual or winter annual to short lived perennial that spreads by seed (approximately 400,000 seeds per plant).
Annual weeds complete their lifecycle in one growing season. Annual weeds spread by seed, and therefore must be prevented from producing seed.
Classification: Noxious Weed
Stem: Highly branched, bushy, smooth, up to 1 meter tall
Leaves: Alternate, very finely divided into thread-like segments, usually hairless
Flowers: White and yellow, daisy-like, solitary at the ends of long branches
Distinguishing Scentless Chamomile from Ox-Eye Daisy and Pineapple Weed
Scentless Chamomile is commonly confused with Ox-Eye Daisy when in flower. Scentless Chamomile is easily distinguished by the finely divided leaves and bushy growth.
Scentless Chamomile is also confused with Pineapple Weed when flowers are absent. It is easily distinguished by the lack of odor when leaves are crushed (“scentless”), while Pineapple Weed has a distinctly fruity odor (“pineapple”).
