I wonder if anybody knows what this is? It's a self sown seedling, I
have 3 of them and I'm sure I've seen more seedlings when weeding so
it could probably become a nuisance if I'm not careful. I'm quite
happy to have a few of them around though - I quite like it and it
grows in some of those difficult to plant hot dry poor places.

There's also a selection of recent photos of my garden in that set.

To me it looks more like Willow Herb. I've seen it as a wild flower
in many places but I have grown the white version, which is very
pretty but invasive. I would say willow herb rather than purple
loosestrife. May be wrong, blame my eyes if so.
