In the corner of the back garden among the Rose Hips in the hedge I spotted.............
"The Robin's pincushion is a red, round, hairy
growth that can be seen on wild roses. It is caused by the larvae of a
tiny gall wasp that feeds on the host plant, but causes little damage."
Or maybe the explanation by Cecily Mary Barker in her Flower Fairies of the Autumn book is the real one.
Many thanks for comments yesterday. I'm sure I'll grow onions and squash again next year. That's the best thing about growing your own..........there is always next year and anyway I like the little bit of independence - even if it is just 1 squash!
