Los Angeles used strangler figs because they grow really quickly. They also drop dew when they're stressed because they tend to get infested with aphids really easily. Which means 20 years after someone thought it was a good idea, there are these massive Totorotrees everywhere whose wood is made out of depleted uranium, whose foliage covers a 30' circle with sticky varnish and whose roots... I mean, they patch the sidewalks around here in the PNW when they're about an inch or two separated. In my old neighborhood in LA I measured a 13" height difference between sidewalk tiles, and then gave up because within a mile I found dozens that were taller. Then they hauled the space shuttle through and needed to cut them all down and everyone got super-salty because they figured they wouldn't get replanted. To the best of my knowledge they didn't.
