This picture of the Dandelion and the green Ground Ivy leaves was taken on January 12, 2005. We had several inches of snow the next day.
I believe the flower in the following picture was some species of Aster that graced an old sandbox in our backyard this past autumn.
This specimen might be a remnant of a Motherwort plant, Leonurus cardiaca.
