This is a client in the city that doesn’t do much gardening, knows that it is important and has an assistant to help him with the actual work.  I referred him and her to Flora Grub Nursery over on Jerrod.  I had been over there a week ago and their displays of succulent walls, Tillandia (air plants) in blown jars and many other exotic and common plantings were spectacular.  The place was buzzing on a Saturday and the staff is really helpful. Here is the info.
