Is this a weed?

I think i dug it up and potted it when i was bored but i cant remember.
Any ideas please anyone?

 

Yes weed Ziggy will name it for you I think it has pink flowers

Like the ones in the paving cracks

Spruce

 

Looks quite like willow herb, but are the leaves furry? If so it is something else

 

will come back to this one with better pics brb

 

Valerian perhaps?

 

I thought willow herb too. Love it when its at its best - tall pink spires and all that furry fluff afterwards.
Yeh, love it when it's nowhere near my garden,

 

Us Gardeners are strange though, cos at my gardening club people buy the White flowered one, but as soon as anyone sees the pink flowered one we pull it out

 

I'm pretty sure its willow herb too. But back to the original question, is it a weed, well no. You've kept it and potted it which means you can put it where you want it. As a weed is only a plant that grows where you don't want it, and you can put that one where you like, it is not a weed.

The willow herbs have pretty flowers but seed everywhere. Just cut the tops off when the flowers are about finished before the seeds take to the air. I think they're annual, and they are quite shallow rooted so they're dead easy to control.

 

Here is one growing out the drive...doing better than the one in the pot

I think you are all right about it being a willow herb? Is it the same stuff you see growing all down the sides of motorways in summer??

 

You see it everywhere, so the side of motorways would be fine too I guess. You see a lot of them beside railways for some reason.

 

Looks like Epilobium hirsutum. Common name Great willowherb, hairy willowherb etc.

Not to be confused with Rosebay willow herb, fireweed. Epilobium angustifolium/syn Chamerion angustifolium.
The leaves of which are not opposite.
This is the very common one along railway lines.

Thats the one i was thinking off that grows near motorways and train tracks like Clueless said?

 

Leaves are wrong for Epilobium angustifolium. Sorry!...see post above.
