The naughty bits of tiny flowers

I’ve no idea what this is. The flowers are tiny, and mostly it’s just foliage. I’m not sure whether I photographed them last year. I think this was a new plant last year, and was quite small when I got it, but has now expanded to fill the whole pot it is in. I’d be happy if someone could tell me what it is.

Anyway, it’s been another busy day of online meetings, with more pieces of the jigsaw falling into place. I think we are now there.

I went out for a head clearing walk at lunchtime, but still got my blip - again - on the balcony.
