Field Guide to Noxious and Other Selected Weeds of British Columbia
Scentless Chamomile
(Matricaria maritima)
- Provincial Noxious Weed
- annual to short-lived perennial; white daisy-like flowers 2 to 3
cm across; grows from 15 cm to over 1 metre in height; fern-like,
very finely divided leaves
- whole plant is virtually odourless (scentless) when crushed
- can produce 10,000 to 200,000 seeds per plant
- often confused with stinking mayweed (Anthemis cotula),
oxeye daisy (Chrysanthemum leucanthemum) and
pineappleweed (Matricaria matricariodes). Stinking
mayweed has a very offensive odour when crushed as well as stem
hairs below the flower heads. Oxeye daisy has flowers to 5 cm
across, rhizomatous roots and entire, notched leaves.
Pineappleweed grows to 16 cm high, has no white ray flowers and
has a distinct pineapple odour when crushed.
