Similarly (and as an anecdote), I have seen cherry blossom trees blooming in the wrong weeks of the year where I live in southern Brazil. I live across a garden-ish square with dozens of them right across the street. The city is sprayed with https://en.wikipedia.org/wiki/Handroanthus_albus https://en.wikipedia.org/wiki/Handroanthus_albus too — as I have one in my front yard — and every year I notice the blooming season shifting a bit, to the point that we are now in late October and the yellow blooming is either quite late AND timid or even inexistent because the tree decided to flip the bird (pun intended) to the weather changes.
