Phoenix landscaping style

One would hate to be a shrub in Phoenix. 

No freedom of expression here. These shrubs, like the children of controlling parents, are trimmed into submission on a very regular basis. 

Even the roadways are lined with shrubs which are trimmed into rigid uniformity.

I don't know who they get to trim the millions of shrubs in Phoenix, but they don't miss a one. One the freeway interchanges, more shrubs, not a one of which is allowed to grow free. They're all little perfect round balls. Or cylinders. Or something unnatural. The place is like a moon colony.

Tucson, meanwhile, is the exact opposite. Informality rules.
