Urban Design

Clean.  Unique. Repeating form.  This summer in San Diego during our Comicon adventure, I spotted this cool feature on the stairs of the convention center downtown.

Stepping back, this whole section added a little color and form to the drab staircase next to it.  But what I loved most about it all was how it was set up.  Here in Tucson, this look can be achieved with many of our cacti and agaves.  In San Diego, you have a large succulent choice.  I currently use this idea with our cacti garden.  Do you use repetition in your garden?  How do you do it? And what plants do you use to accomplish this look?
