The sun is starting to peek out after the rain, but it hasn’t cool off nor has the dewpoint dropped, so it is another hot summer day. The yellow blossom of the common St. Johnswort looks like the sun bursting out its rays. But like many other flowers, this native one from Eurasia and North Africa was introduced into this country in the 1700s as an ornamental and as a medicinal herb. Now it is considered an invasive and noxious weed especially since toxic to livestock as it crowds out native species and forage on pasture lands.
