I'll throw in Hyssop (agastache). Here's mine for comparison. I planted it from seed but didn't like it because I was expecting one if the fancier Agastache's. It grew on me eventually. Self seeds and moves itself around quite easily. And mine has a very square stem.

27,30 and 34 are common buckthorn (probably 31 and 32 as well). Probably one of the most invasive woody plants in northern IL. I would recommend removing them and any others you might find and planting something more desirable. It is a good investment in the long run.

I thought the first were lilies, but my mom said they looked more like aster leaves. After I looked at her lily foliage closer, I thought she might be right. Can you tell me what type of lilies? Amaranth...it does look a bit like it. I'm in Minnesota;; would there be a type of amaranth that would outlast the winter? I grew some from seed myself this year and it does certainly resemble it. I will take another photo this evening. It's very low lying and spreading. Thank you

We’d love to help you but we need close up, in focus pictures and a geographical location.
