msslynne I see wooly thyme(soft and cushy to walk on, smells of lght lemon), mother of thyme-mine is like the purple red here, and maybe a bit of lemon thyme on the pathway and some babys tears or blue star at the bottom-all of these grow easily, quicker than you may think and require no upkeep-huge plus in the pacific northwest they mind neither sun, rain nor our winter weather-mine are all planted in soil/sand mix past the 1st 2 wks I have never watered them. This is a gorgeous picture!
