Close up of the stems and leaves.

If this is a plant you do not want growing where you do not want it growing it is a "weed". What it is does not really matter at this point if you don't want it.

"Weeds" are just unloved plants.

I guess I should have posted at Name This Plant. Anyone recognizes this as a known weed?

It looks as if it will flower soon. That will help us id it. At the moment is looks vaguely like Linaria purpurea but I've not seen one do dense and semi prostrate. If you could say where this is growing it would be useful.

I transplanted it from my seed tray. There were a couple dandelions that landed in there voluntarily too.

In what area of the world are you?

Yes - when I said 'where' I meant geographically ;-)

Found a bloom today. Any one recognizes this plant?
