I understood, having seen Hayward's post, that some kind of year-round plant wall would be possible in Chicago. My point was that offering any example from Madrid -- without commenting whether the example would also survive somewhere very cold -- was pretty useless, since Madrid's average low temps are above
freezing all months of the year. Chicago has a big fraction of the year with below-freezing nightly temps and of course weeklong stretches below freezing. And then we add the fact of the exposure to the open lake.
Also, a general question, is it more challening for all these vaunted prairie grasses to survive in a vertical installation (which also won't be tended to as carefully as, say, the city does the street planters)? I'm not familiar with how they are planted in that vertical configuration.
I mean, if it hasn't been done long-term before in Chicago (please point out exceptions if that's wrong), isn't it reasonable for one to conclude that this render's exuberance is more property marketing folly than realistic?
