@Rojertb
Of the general category of "municipal grey-weed", usually found in an ankle-high verge to a public space with the flowers poking above a layer of litter.
@Rojertb it is😊 I’ve got one outside my front door! It’s brutal on your hands if you try to cut down!
@Rojertb ….despite the ‘Japonica’ nomenclature they came originally from China. The berries a can be used to make jelly, or a jam I expect.
