Trends like this are essentially like fashion, but applied to gardens (well, the area around your house, I guess at one point it stops being qualified as 'garden'). I.e. pushed by industry/magazines/..., copied by people seeing other people doing it etc. Usually goes in cycles so in a couple of years it might be different again. Hopefully not lawns again, but actually I don't see it impossible that just like in fashion, what is now sort of subculture becomes mainstream and gets adopted by the masses and we'll get a ton of wild gardens.
