Shrubby St John's Wort

I've had a lot of this spring up in my garden this year (mostly at the edge of walls or patio). I quite like it but have read that it's an invasive plant. Should I get rid of it?

Angie, I have it in my garden - unfortunately - and it IS invasive and it IS difficult to dig out as its roots seem very tenacious.
