In the floristic area, cow cockle is currently known only from a few road cuts in the Lucky Peak area.  However, Bernice Bjornson had this this to say about Vaccaria in 1946:  “It may seem odd that a plant with such a pretty, rose-colored flower should be a troublesome weed, but such is the case.  Vaccaria [hispanica], cow cockle, has been introduced into this country from Europe and in the prairies is the bane of the wheat farmers.”
