Perhaps the first one is Anemone quinquefolia or something similar?

Yes, the first is probably Anemone lancifolia (which has 3 leaves,, as compared to quinquefolia which has 5 leaves).

Flower looks like a ranunculus. But I don't know which one.

I think the second one was ID'd here recently?

If so, I could not find it. Do you remember when?
Thanks,

the second one looks some what similar to one I posted recently which was identified as Wedelia . I have no idea if this is the same thing but it might be what was seen recently here.

By Jove, that's it.Compared online photos to more of my photos and that is definately it. There is a similar plant that only blooms in the spring
