Solved What is this tiny invader please?

It's very pretty and grows in the cracks of the brick wall (below seen through Jasmine) and paving. I have seen it colonising tall walls.

The colour is in fact more purple than in the pics. The wall is in shade so the leaves are much bigger than when it grows in the paving.





Thanks!

 

Cymbalaria muralis.....common names ivy-leaved toadflax, Kenilworth ivy etc

 

I had some of this 25yrs ago growing up a fence, then it got wiped out by a very cold winter.
Never saw it for years, until I noticed it growing in the very same place it used to be.
A seed that had lied dormant must have germinated.

Looks much bluer in the pictures than what I have.

 

Thanks everybody!

I googled it, seems like a very welcome addition to my garden.

What is it with common names? Quite a whack for a small plant :

Other common names

It is a bit of a weed.
