Does anybody know what this tiny wildflower is? It was just 1/4 of an inch across when fully open (about noon). It was fully closed by about 6 o'clock. It has the smaller, oddly shaped leaves, with the stronger veins. (The larger leaves that you are seeing are pachysandra.) It doesn't seem to be very invasive, since I've never seen one before.
This plant is in Norfolk, Virginia, USA. It is in a protected spot just around the west corner of my house, where it receives strong southern afternoon/evening sun.
The original flower here was living under a gutter downspout, and was decimated by a recent downpour. But, I did find the same thing growing nearby after my friend weed-wacked. The leaves and the stems look the same, with the furry edges. Also, I remember that the smaller leaves had an even shape, while the larger ones grew into an asymmetrical shape. Perhaps this pretty wildflower/weed is more common than I thought! I'm going to try and add the new leaf pictures (as requested), now.
