The second plant isn't a fern. Can you see how there's a with stems with lealets off of it? The second one might be a Geum, but not at all sure of that.

Thank you, peren.all. I wasn't sure the leaves quite matched R. acris but I know leaves often change with age so you can't always expect that photos will exactly represent what you have. Thank you, jekeesl (south-central Arkansas). I don't think there's any doubt that you are right about plant 2 being a sedge. I promptly went to a wild plant site and searched through a list of--I don't know, maybe 10 million--species of sedge that grow in Michigan and narrowed it down to two that grow in Lenawee County that, to me, look similar: Carex hystericina and Carex frankii. C. typhina wasn't said to grow in this county but it does grow in the county next door and it looks very similar.

It certainly looks like it. I don’t know of another name or cultivar. Some plants that start out with more variegation will be more green later in the season. I don’t know if Hydrophyllum is one since I have only seen it in spring. Did you realized that there is a very active plant ID forumcalled Name that Plant here on Houzz and Gardenweb? You will get answers much quicker there, and if you repost there may get more information than I was able to give you. Name that Plant
