I am happy to have any excuse to visit a place in Oak Openings we plant monitors call Butterfly Meadow. It is a beautiful field that holds many of my favorite plants.
We were there today to count this little fellow, the Lance-leaved violet. Since it is listed as only a potentially threatened species in Ohio, we don't count it every year. It is found in moist, sunny areas. The leaves are the thicker of the two types seen in the photo.
The flower measures approximately 1 cm. across. The bloom is over in a few short weeks. By then the surrounding plants have grown so tall, it is impossible to find.
