I'm hoping someone can identify a plant, I picked the seedheads from this in Suffolk last year (outside Beccles Lido - I now refer to it as just "Beccles Lido Plant" , I think around early July time. They were tiny blue flowers a bit like Lavender , the plant itself was growing out of a wall and the dried seedheads looked a bit like miniature hops. The bees seemed to like them hence I got some seeds.
Anyway a lot of them have come up this year, but I'd like to know what it is. I've attached a picture, you can just make out the purple/green leaves, the largest one you can see is about 1.5" across.
Any help will be much appreciated!
