What are these flowers?

We have some ground cover flowers we were given that are very pretty and actually are doing a great job covering the ground where we needed it ... behind our shed.

However we have noticed that they are taking over... We are trying to find out how to stop them.

(1)

Here they are where we wanted them. Behind the shed

(2)

Here they are in front of the house spreading

they are choking out the other flowers here.

(3)

Here they are taking over my Strawberries.

(4)

Here they are in the Grass near our neighbor’s yard, after I mowed them off.

Anyone know what these flowers are?

We can't remember!
