DAY 223 (14 NOVEMBER) – Mountain grape? (Berberis aquifolium) (Farnham)

Gosh, the sight of these bright flowers against a sunny sand-coloured wall made me think I was back in summer. But the real mystery is what they are. Plantnet says they are mountain grape, but they are supposed to flower in spring, and don’t seem to grow on long spears like this. Anyone?
I don’t care – I loved them anyway.
