Oak openings today? We will see if the weather allows it. Oak Openings is a region of ancient lake bed west of Toledo, Ohio. Just a few miles south of here, but so different. Many species of plants grow there that would not usually be expected in our region. This Allegheny phlox is one. It has been found only once in Michigan. But Oak Openings has them in some numbers. Or maybe we will see northen clubmoss, another rarity. Or maybe we'll just get wet.
