Greg, I don't know the particular cultivar of that little stonecrop, but it is likely a very common one. It pops up all over in my garden and I often just let it be a groundcover wherever it decides to land. Probably travels on my shoes or tools. White flowers. Does best in full sun but tolerates some shade. Pretty much evergreen, as you can see. Really likes to tumble over the rocks, and then grows in the cracks of the cement below. Happy little plant.
