What can you plant between pavers?
Haven't a clue on the plant between the stones. Suggest using something that grows well between stones in shade, required little or infrequent mowing. Baby tears? Dicandra? Sunnier climes perhaps a prostrate thyme or chamomile?
The beaten path. If the only truly green space you can create is around your sidewalk or driveway: make the most of it. These stones were simply shifted left and right when positioned, but effect goes a long (and nonintrusive) way.
If your area is sloped just ever so gently, consider a beautifully landscaped path instead of steps. This would be much easier to navigate than lots and lots of short steps. What a fabulous design...very unique.
