Is the Portulaca Grandiflora also known as 9 o'clock flower?

I had them at one time in my yard. They were yellow in color and would bloom at 9am and 9pm. About 15 minutes prior to 9:00, the flower would begin shaking. I would love to find these seeds somewhere.

Is the Portulaca Grandiflora also known as 9 o'clock flower?
Yes, but there are other flowers that are more commanly called this. The most common name for the Portulaca is "Moss Rose".



You could also be thinking of a plant called "4 o'clocks" which look like this:
