Please can any one advise if this is a weed  or what is it?

i get lots of this in my garden, if you leave it it gets purple flowers on, if its the same one im thinking of, you could call it a wild flower, i just pull them out, they come up easily enough

Willow herb?  Increases by seed and underground spreading roots.

Thanks  for your relies, they have gone a little crazy in one border so perhaps I will pull some out and leave some to see what they turn in to!

If it is willowherb, and it does look like it, possibly rosebay, there'll be underground runners. Your plant looks like it's from a runner. Look for horizontal roots below the surface

Looks like Willowherb, if you do let it flower, don't let it go to seed - it'll be everywhere next year

Aargh the dreaded rosebay!

It's also perennial. Keep yanking it out or it'll be everywhere. Each plant produces around 80/100,000 seeds....

Thank you, pulled a few out, wondering if it has come from a wild flower mix I put in last year!

Ah the eternal question, what is a weed?  The discussion earlier in the week over Dandelions seemed to split the group in two, with those who remove at any cost and those who love and leave them be.

My favourite "weed" is the Nettle. My nemesis is Bronze Fennel, 

The definition of a plant in the wrong place is pretty spot on

Rosebay willowherb grows about 3ft (don't do metric) tall and is food for the elephant hawk moth caterpillar.  The adult moth is large and coloured pink and green.  Some years ago when I worked for the then Ministry of Agriculture, two small boys brouht in a caterpillar which they thought might be an 'agricultural pest' and I kept it in a large jar  (called it Hannibal) and waited for it to pupate and eventually emerge into this beautiful moth. I released it onto some waste ground with a healthy crop of willowherb growing there.
