I grew a few sunflowers in the summer. Despite the dry (near enough no rain at all from July to September) they grew tall and strong and produced enormous flower heads. I left the flowers on, fully expecting the birds to eat all the seeds, but by early November they had hardly been touched, so I picked the two largest, the size of dinner plates. The rest I left on the plants, and the birds have at last moved in on them.

We've got about 4 apéro nibbles bowls worth out of two big sunflower heads. Simon commented that their calorific value needs to be substantial to make all the work we've put in processing them worthwhile. These sunflowers, like the cherries and the hazelnuts before them, make me appreciate why some produce is so expensive to buy in the supermarket - they are really labour intensive to process.
