Some of my garden shots have had some perforated concrete pavers shown in them. In case you’re wondering what it is, it’s called Turfstone, and is one of several products out there that are designed to allow you to have a lawn that you can drive onto.

The basic idea is that you interplant the little holes with grass, and the concrete blocks keep vehicles from cutting ruts into the lawn. You of course could also fill the holes with other kinds of plants.

If you don’t want to have to water your driveway, or if you want a sturdy but porous material to use to cover a French drain–which is what we wanted–you could fill the holes with material like crushed rock or pebbles, as we’ve done here. Using a contrasting material brings out the interesting grid pattern.

The material is somewhat specialized, so you local home store probably won’t have it in stock, though they may be able to order it for you. Failing that, the blocks seem to have a pretty wide distribution so that a landscape materials firm could probably find it for you.
