phlox drummondii, one of your natives.

Bottom one looks more like Linum grandiflorum 'Rubrum'.

Yes, that is possible as it is also a native there, and looks quite a bit alike as far as photos go. Phlox flowers last multiple days (temperature and water allowing), but linum flowers but a few hours...but I can't tell that from a photo either.

The centre of Linum is quite distinctive from the Phlox and the buds unfurl differently too. Top two are Phlox. No 3 is Linum.

Ok, I certainly won't argue. Always fun when an id has multiple plants that aren't the same.
