Name: Dave Dayton, TN (Zone 7a) Blessed beyond all merit.
About 4 years ago my wife bought and planted this bloomer. She didn't keep the label so I have no idea what it is. Flower opens in the morning and closes in the evening. It does this almost continuously until it dies back in the fall. It its cloudy or raining the flowers stay closed. It is very late in the day so the flowers are closed in the first photo. The second photo shows how it grows from the ground and the third shows its clumping habit. Hope the photos help some. Sorry about the poor quality but didn't have time to set up the other camera.
