This is a commercialized version of a technique used by the "guerrilla gardeners" movement that has taken root in many blighted cities. The idea is that there are many vacant, ugly, fenced-off, lots that the owners/flippers have no plans to do anything about—so you might as well try to add some nature since local residents are the ones who have to look it at.

That's some background, I guess it's HN worthy if you are looking into various sub-cultures for ideas to mainstream in a popular marketplace.
