Pop-Up Planters Sprout Up Around the Streets of SF

King describes these so-called "parkmobiles" as "portable landscapes in red steel bins 6 feet wide and 16 feet long, intended as a shot of mobile nature offering passers-by visual relief from asphalt and concrete."

"The parkmobiles signal San Francisco's most ambitious effort yet to improve the large, urban landscape in small, fluid ways - an effort set, tellingly, in a district that symbolizes old-school urban renewal."

At $6,000 a piece, the mobile landscapes are an example of an innovative, low-cost initiative taken on local property owners and CMG Landscape Architecture in the Yerba Buena District.

"The hope is that the bucolic bins will draw people onto blocks that otherwise get little foot traffic – and that the design and vegetation will survive the moves and the crowds."
