Walk-On-Me Plant is a creeping thyme that grows only 3" tall. (Also called Mother of Thyme). Plant around flagstones or for a decorative, dense-growing ground cover. Walk on it and the whole area will be filled with the aromatic smell of fresh thyme.
Remember Hugulkultur in creating raised beds. Since I like the higher beds, filling the bottom half with prunings and such will reduce amount of topsoil needed to fill bed.
