Oxeye Daisy / Chrysanthemum leucanthemum

I'm surprised that there is any clarity in this photo, as the mass of Oxeye Daisies at the side of the road was blowing in the wind when we saw them, shortly before reaching the Takakkaw Falls, near Field, British Columbia. They are beautiful flowers, but unfortunately they are also an invasive weed. Status in Alberta is Noxious.

 

"Introduced from Europe in the early 1800’s primarily as a grass seed contaminant, and subsequently spread as an ornamental, Oxeye daisy has become a serious invader of pastures and natural areas throughout North America. It is a perennial herb that reproduces both by seed and shallow rhizomes. Single plants quickly become patches that continually increase in size. Plants flower June-August and its seed germinates throughout the growing season. Oxeye Daisy and the very similarly flowered Scentless Chamomile can be considered conspicuous, as there are no native white flowered daisies in Alberta."
