ID please

Hi everyone,
i have a small plant in my garden that seems to be popping up everywhere, they are growing in little groups of leaves, i have looked at the weed id's but im still not sure, i dont know if anyone can help me i might keep them if they are ok but i have quite a lot of them and am starting to worry a bit...
Thanks Gill

 

It looks like leaves of a wild Voilet. Viola sp.
One such as Viola riviniana.

I'm glad I looked in here as we have this to around some slabs & near the green house very small & beautiful purple & white. I thought that was a flowering weed lol. oh well I'm learning a lot from here

 

If the flowers are purple and white it might be Viola tricolor. Common name Heartsease.

They are a PAIN to get rid of. I've been trying to pull some from an area where they are NOT wanted one the leaves just come off leaving the roots. If it dries out I'm going for the round up!!!

 

The flowers smell lovely but it spreads everywhere in my garden too. I haven't gone down the chemical route - yet...

 

Just took a quick pic its not blue & white as I thought

 

They do vary quite a bit.
Still a Viola. More than likely Viola tricolor.

Hi all
Thanks for everyone's input. I was a bit worried that it could be something invasive ,
But as my garden is more or less a small wild patch only a few meters big I think I will
Take the risk and leave it it's does look a pretty little thing
Thanks everyone
Gill
