Last summer, we took a look at a gridded concrete outdoor space with grass for grout between individual concrete squares. With this summer upon us, we're looking at the idea in a little more detail and were wondering what plant species specifically would work well between stepping stones:Creeping thyme is often used because it is a low, spreading plant that holds up well to foot traffic grazing above from stone to stone. It doesn't need very deep rooting and as a bonus it gives off a fragrant smell in your outdoor space. It is suitable for use in zones 4 through 9, which covers most of the United States.
The gallery above includes some examples of creeping thyme used between stepping stones for a little further visual inspiration.
