Weed Id.

This is taking over the Bowling Green. Persistent roots and seems resistant to broad leaf weed killers. (Not that the greens keeper is keen on using chemicals while the bowling season is on for obvious reasons).
Not seen any flowers either.

 

Is it ragwort?

Flowers are only produced in the second year and after the flowers it produces lots of wind blown seed that allows it spread easily.
Happy gardening!

 

Ragwort is a possibility, but this spreads by runners as well and Ragwort is not supposed to.Thanks

 

Just a thought could it be Ajuga reptans (Bugle). Mowing would stop the distinctive flowers from forming and also keep the plants small. Spreads by runners.
Just something about the leaves especially the first picture made me think of bugle.

 

Now that really does look like it. There would be no flowers as the grass is cut very short and regularly as you would expect on a Bowling Green.
Thanks a lot!

 

Another suggestion is Germander speedwell. We have planted some of it in pots and will wait to see if it flowers.
