I think this is the coolest garden stairway I’ve seen yet.  The buffalgrass tolerates moderate foot traffic, and it lends a fluid look to the otherwise hard edges of the steps.  And you can’t tell from looking, but it both felt and sounded silky.  Best of all, it doesn’t require mowing.  (This is the Rolston/Cohn garden, part of the garden tour put on by the GWA in Dallas last week.)
