Just a couple of years ago, if you wanted to make something look trendier, you put a bird on it. Birds were everywhere. I’m not sure if Twitter was what started all the flutter, but it got so bad that Portlandia performed a skit named, you guessed it, “Put a Bird on It.” (“What a sad little tote bag. I know! I’ll put a bird on it.” Etc.)

It turns out architects have been doing the same thing, just with trees. Want to make a skyscraper look trendy and sustainable? Put a tree on it. Or better yet, dozens. Many high-concept skyscraper proposals are festooned with trees. On the rooftop, on terraces, in nooks and crannies, on absurdly large balconies. Basically anywhere horizontal and high off the ground. Now, I should be saying architects are drawing dozens, because I have yet to see one of these “green” skyscrapers in real life. (There’s one notable exception—BioMilano, which isn’t quite done yet.) If—and it’s a big if—any of these buildings ever get built, odds are they’ll be stripped of their foliage quicker than a developer can say “return on investment.” It’s just not realistic. I get why architects draw them on their buildings. Really, I do. But can we please stop?
