Anyone know what these two plants are?

The second one with the mauve flower is a campanula, the first one looks like it might be a dahlia to me.

Dahlia and campanula

Ooh lovely! Does dahlia usually grow as a weed? I’ve not had either of these in the garden before!

Does dahlia usually grow as a weed?

No!

ErrolTheDragon I didn’t think so! I wonder where it’s come from then...

You've got creeping cinquefoil and creeping buttercup behind the campanula though, both of which are very enthusiastic weeds!
