Identifying Plants in Photos?

How do Forget Me Nots as young plants look so I don't mistake them for weeds? And is the plant in top photo Japanese knotweed? How about the plants in other two photos?

The top photo, pink is a fuschia.
The second is wild/natural geranium I believe
I don't know what the 3rd is

No knotweed in those pics

Third pic has nice pale blue/purple flowers, but can't remember what it's called. Spreads like nobody's business. Smells like week-old wet washing when cut.
You've got some lavender in that first picture as well.
I am sure you can google "forget me not seedling" if you try hard enough. But I wouldn't worry too much about pulling a few up, because a) it seeds itself all over b) they've all died back for the year by now.

I thought it looked like a Curry plant in the top pic but WNI called it right, i think: lavender it is. Maybe consider clipping it back as the stems look woody and it will become leggy, overshadowing the fuschia in front over time. No knotweed, but that plant has a runner-root, sending out shoots along the line of least resistance, common alongside railway tracks, so i'd pull the buggr out if i were you. Looks like you've got plenty of buttercup along the ground, too. Don't let it get out of control or soon you'll have nothing but in your garden.

Forget-me-nots have a large green head of leaves over winter and will soon show bright flowers in spring, so i try to pull 'em in autumn to avoid having them all over the garden. Damned seeds stick to anything and spread like plague. I don't see any in the pics.

You could try inserting them on google images and it will identify them for you.
