Nature loves a Fibonacci series

My workshop went well. A little clunky on my delivery as this was the first time I have given this particular talk. But I think there is a nugget there, with the art of noticing, that I hope to refine.  On a completely different topic, these winter stems are compelling, aren’t they? Those dots are not burs,  and I don’t know what the plant is. Wild mint, perhaps? Anyway, one thing I am sure of is that those little dots (calices?) are very probably laid out in a Fibonacci series.  Nature loves a Fibonacci series. And so do I.
