OK, this isn’t the ingredient list for a Witch’s Brew. Just a couple pictures of natural and naturalized landscaping.
This is Oxeye Daisy (Chrysanthemum leucanthemum or Leucanthemum vulgare). As often as I saw it, I used to think that this was native…and a quite beautiful prairie forb. It’s apparently native to Europe and considered an invasive weed in some parts of the United States, but it is a common inhabitant of horse-battered fields in Missouri. It looks like battling Oxeye Daisy with prescribed fire could deter its growth. A prescribed burn and native replanting would ensure it and other invasives are less likely to return. Grow native!
