Last may be Tanacetum parthenium

For the last one I'd say Artemisia vulgaris. T parthenium would have a very strong smell. Does it?

I do think Viburnum trilobum and Zizia aurea might very well be right. Artemisia vulgaris looks like a possibility. The plants are blooming. Do the leaves on T parthenium have a strong odor?

Thank you all!

Yes, like very strong Chrysanthemums.

Did you mean you say the plants aren't blooming? Because if they're in flower it'll be obvious what they are.

Artemisia leaves have a silver reverse.

Agree, viburnum, zizia, and possibly a chrysanthemum?

Mugwort, Artemisia vulgaris, was my first thought on the bottom plant as well. I just yanked a few plants up earlier this year. And yes, check for the silver undersides.

I am not so sure that it is mugwort, having fought a battle against that for years. Tansy seems more likely to me.

If it IS mugwort, you may want to warn the Dominicans that they'll be looking at only mugwort in no time at all.

It is easy to know if it is mugwort as previously stated above by two of us. Not complicated at all.

Imo it bears little resemblance to Tansy. It might be Feverfew. If the OP would check for the silver or the strong smell the mystery would be solved in a moment. But my money is still on an Artemisia.

floral-uk, I will definitely try to find it again, soon.

Here is another photo of the plant most of you think is mugwort. It does have a rather strong smell (not unpleasant) and the back of the leaves is sliver, as you see here.

Mugwort. No question. The smell is nothing like as pungent as Tanacetum parthenium.
