Weed or plant, plant or weed?

[cathyandclare]

What is this tall plant that has popped up in a shady, woodland border? It's somewhere where I vaguely remember planting something... but it looks a bit weedy, kind of like a sort of dock but not IYKWIM.
Any ideas gratefully received

Teasel?

From just googling I wonder if it might be Enchanter's Nightshade.

Looks like it needs to be terminated anyway!

Possibly teasel. Did it start growing from a sort of rosette of leaves at the base?

Definitely Enchanter's nightshade, difficult to eradicate, as it spreads from any root fragments left in the soil ( I have it...)

Thanks! The only things that grow in our garden are invasive weeds, i wish the bloody rabbits liked nightshade instead of all my lovely plants!
