Is this a weed or a flower?

[JScott]

I have this plant growing very well in my flower bed. It's actually quite attractive, and growing well. The thing is, I don't remember planting anything there! So is it a weed? Or a flower?

Honestly, I find it attractive enough, I'll probably leave it there either way, but I was hoping somebody could identify it. Take a look at the pictures, and see if you recognize. I appreciate every one of you and all the help you've given me through the years.

the OB is being weird and says I cannot upload files because a security token is missing. I have no idea what that means, so I've linked you to the pictures in my google drive. I know that's more annoying than having the pics right there on the post, but it's all I could figure out to do:

Update your browser to use Google Drive, Docs, Sheets, Sites, Slides, and Forms - Google Drive Help

What? I don't know what that means. If somebody can fix the security ticket thing, I'll redo the post in the standard manner. Sorry guys.
