Ground Phlox with Yellow, sweet scented plant

Euphorbia Lori ,it looks very much like one I have called 'Tiny Tim ' to be honest I have spent ages today pulling it up as it's travelling so fast across the garden it's in danger of smothering other plants .. !

Euphorbia? thanks!...and he sure is a traveller. I don't mind at all...I think I have a million spots tiny tim could spread to his heart's content!

I don't think it's Euphorbia, Amy. it has lacy foliage and tiny little yellow flowers on top of a single stem...no branching...but it does spread very quickly...still looking...thanks just the same! ;-)
