Carduus tenuiflorus

Slender thistle, I think.
I planted a block of sweetcorn plants on the plot early morning before heading down to CK to exercise Indie. The £8 nest box was a bargain, Mum is getting so much pleasure watching the Blue tits to-ing & fro-ing with food for their brood, which is very close by. The tiny green caterpillars are easy pickings from the willow just over the hedge.
I think I may have started Spring cleaning this afternoon. How did that happen.
