After further research and going through my seed packets, I think these are Sweet William. What threw me off is that I didn't plant Sweet William this year and the green spiky head of the flower is not what I expected Sweet William to look like. Mystery solved at least.
And then there are two of these tall spindly plants with white blooms. They're not so pretty and I'm hoping they're not weeds. Any and all clues to the identity of thesep lants are most appreciated!
