Going by the structure of the leaves and that one cluster of flower buds that are forming I think maybe some variety of dill OR a variety of confetti cilantro. But it also has lacy leaves similar to chamomile and pineapple weed which does not have undeveloped flower buds like that but they may change with maturity of the blossoms, and the pineapple weed plant is a wild medicinal herb related to cultivated chamomile.
In any case whatever it has seeded out from, be it wild weed or cultivated culinary herb, you may need to wait for those flowers buds to finish developing and open up before you can confirm. In the meantime, rub some leaves between your fingers then smell the leaves and your fingers to determine if the plant oils smell anything like dill or cilantro or very mildly of pineapple or of chamomile tea. Taste a small leaf, chew it up well to get the full flavour of the herb. Watch as the flowers develop to full bloom and if not yet identified then post pictures of the opened flowers or any seed pods on the mature plants.
I knew I was missing something out and it finally came to me today when I picked up an Artemisia Abrotanum ‘Cola’ plant at a local specialty nursery.
Here are two additional possibilities for your mystery plants.
One is Cosmos which has leaves like yours but gets bigger flowers, in some varieties the flowers are produced in clusters like that cluster of buds you have on that one plant, others are produced on individual stems: https://www.google.ca/search?q=Cosmo...h=583&biw=1120
And the other possibility is Artemisia Abrotanum, a.k.a. Southernwood, (a relative of Wormwood) which like most other artemesias are highly valued traditional medicinal herbs that starts off small like yours but grow into big plants that produce relatively small flowers. Today I brought home the "Cola" variety: Artemisia Abrotanum ‘Cola’ – Cola Herb – Southernwood – MY GARDEN
** A little hint for you - most of the time whenever you come across plants that have those lacy leaves like that, whatever they are they usually serve some important medicinal or culinary purpose. You just need to get a positive ID on them and research their properties before treating with them according to their properties.

Thanks, Zoisite! Among the possibilities, I think pineapple weed is closest. All the lacy plants now have buds. Assuming the buds do something, soon we shall know (or at least, know more.)
If it's not too boring, I have an update. I am very glad I did not weed these plants, because they are producing delicate flowers. What a nice plant--lacy foliage, and delicate flowers.
The plants are covered with buds, so I hope it will be very colorful soon.
I went to a botanical garden in Princeton and saw entire sections given over to this plant, but it started to pour before I could find a plaque to identify them. I will have to go back.
I have a picture of the flowers, and one that is covered in buds.

That's rocket larkspur, a type of delphinium. There are other delphiniums that have different kinds of leaves too.

That's quite pretty, grats. BTW someone once told me the only difference between a weed and a flower is how you feel about a plant. I tend to agree.
Thank you so much. I agree as well.
