Bullrushes and a profusion of other water-edge plants at the Botanic Gardens in Edinburgh.

@LillyHerself I think those are (mostly) teasels: Dipsacus fullonum. https://en.wikipedia.org/wiki/Dipsacus

@stevendbrewer Thanks! I thought they looked more like teasels than bullrushes, but then I couldn't remember the name so I went with bullrushes. 😬
@LillyHerself Teasels maybe?
@martin_fff Correct! I kept thinking "the name's not thistle, but something like that", but it was late and I was tired so I went with bullrushes.
