July 27 - Fall colours are already beginning to show, with the occasional red leaf dotting the garden.
This article from Harvard talks about some fairly recent discoveries about chemicals at play. It's not always photosynthesis at work, sometimes it is the plant protecting itself from intense bursts of light followed by cool temperatures. Sounds a bit like the what we've been experiencing lately.
Weather-wise, it has been a strange summer, with floods, and heat-waves followed by chilly days.
