They are very beautiful with their smooth, semi-gloss melon green fading towards the base to pale yellow and ivory and with a tiny point at the top. Some have fallen still inside their cups of dusty grey embossed with darker markings like antique bowls.
After a few days they turn nut brown, but keep their shine, and provide a welcome food source for various animals and birds: mice and voles, squirrels and wild boar, jays and woodpigeons. There are insects too - acorn weevils and some tortrix moth caterpillars.
There is a round disc at the base of each acorn like a flatbread with char marks around the rim or a stone disc with a mystical circle of characters in an unknown language - acornish. Do all these characteristics have a purpose that makes them 'fitter' than other seeds I wonder. Why are they egg shaped? Why to they sit in a cup? Why do they have a point at the top?
In the autumn sunshine as well as acorns there are buttercup and smooth hawksbeard flowers, but the finest is the late flourish of dandelions with their wonderfully ragged symmetry and a bright, even yellow.
