First is Dianthus, and the second looks like Potentilla

The Danthus looks like D armeria, Deptford Pink.

The last plant is in the same family, the Caryophyllaceae. Perhaps Spergula rubra.

Thanks! None of them are causing much issue right now, but I'll keep an eye on them, and watch for spreading/invasiveness ... particularly the Spergula at the roadside (to make sure it doesn't take over the yard. The other two aren't likely to out-evil the creeping bellflower.

I know nothing about Spergula, but the other two definitely have the potential to spread far and wild. If they will depends on your growing conditions: your soil and your climate. On my property similar to yours looking Pinks are everywhere, as for Potentilla I pull it up all the time.

Thanks -- got a few of the first 2 in weedy areas on/near my lot. Even that tiny, the color of the Dianthus is startling.
