A European import cultivated for fodder, Cow Vetch tends to be found wherever livestock is nearby. The vines twine through other less decorative weeds, and the beautiful blue-purple flowers light up the edges of fields. This patch grew in a sunny meadow near Cranberry, where it was blooming in the middle of June.
