Malva, probably Malva sylvestris (common mallow).

It is both a cultivated flower and a wild-flower.

If it's a weed I want to get rid before it takes over.

Mallows tend to be short-lived, when not annual or biennial. Whether it
will take over may depend on where you are - they don't seed around much
with me. It doesn't spread vegetatively.

I'd be more concerned about the horsetails...
