vertical gardening has really come into its own, and has migrated from commercial and public installations to the front of your house. and, why not? green spaces are becoming more dear as development takes over every inch of the urban/suburban landscape. the maximum green house (above) was recently completed in singapore, where every inch of land is at a premium. i snapped this photo during my recent visit to san francisco's russian hill, where gardening space is also highly valued.
this gardener may have gone a little overboard, completely obstructing the view of their house (i think there is a house in there!). maintenance of this place must be quite a chore!
