Tiny groundcover...... Asarina ???

Hi folks I bought this as an Asarina a few years ago but I've checked everywhere and can't find any information about it.
The only Asarinas I can find are climbers except for one groundcover that is yellow....

 

Looks like Kenilworth ivy to me.

 

Thanks Pete
I've checked it out on tinterwebby thing and yes I think you're right.
I am a bit confused though as some sites list it as a garden plant for sale etc whereas others say it is an invasive weed.
I'm not really bothered though cuz I like it and where it is it can't go any further.
It's in a filled in birdbath and is growing over the edge nicely.

 

PS..... Forgot to say I hope it's not a weed it cosy me about £4.

 

Its one of those friendly weeds.

I had it years ago growing up a fence, but a really hard winter killed it off, not seen it since.

 

Got the name now..... Cymbalaria Muralis.

Pete, if you want one give me a shout later in the summer as I'm planning to try and take some cuttings off of it and I'll send you one if they strike.
