Prickly food for pigs.

With leaves like a thistle but yellow dandelion-type flowers, this is the Prickly Sow-Thistle, one of the flowers still in bloom at this time of year.

With a cluster of flowers at the top it is a fast growing annual, more welcome in the fields at Filnore than in your garden.

The thick, white central vein on each leaf looks almost like Swiss Chard, but I wouldn't fancy chewing these leaves.
