12 Jun Weed Wednesday – Scentless Chamomile
Scentless Chamomile (Tripleurospermum perforatum)
This is one smart plant! While it does look ornamental, it is certainly not a plant you want in your flower garden – even though we often find it there!
This NOXIOUS (which means it must be controlled) plant can act as an annual, biennial or even a perennial and has the ability to flower at varying heights – if you mow this plant it will flower below the height of your mower next time, but it can also grow to be several feet tall and over a meter wide.
While it can flower all season long, its only reproductive method is through seed (up to one million seeds per plant) so if you see this bushy daisy pick it, bag it & burn it. While picking is very effective, once this plant establishes in a hay or crop field it can spread rapidly. Cultivation to destroy rosettes and herbicide applications are required. We often see this species pop up in bale yards and where cows were fed in the winter. If you notice any of these white flowers, be sure to have a look at your crop/hay fields. And when buying feed, be sure to check with the seller and ensure it’s free of noxious weeds like scentless chamomile.
