The Trees Think It's Autumn

Living in a country where there are no native deciduous trees the only real indication of autumn is a drop in temperature and humidity......and visually, where people have planted exotics.
So far we have not experienced the typical climatic conditions with it still being shorts and t-shirt weather.
But the exotic trees (and grape vines) obviously know better.
These are a few of the 'indicators' growing around us.
