The roots would probably appreciate a light cover of soil, compost, or organic mulch add on top. Daylilies don't naturally grow exposed to air like this and while they may well survive, they won't be at their best.

Bidens?

Thank you very much for the ID's. The first one is near the spot where I saw the bad-looking P. mugo subsp. rotunda about which I asked an ID too. At first I though they were both the same species because they looked similar, but when I went too look closer then I could see the cones were definitely different. Funny part is that someone else suggested in that thread where I asked for an ID that it could be P. thunbergii. So I guess both trees are similar looking indeed. The second one I think comes from a hedge close-by that was (I think) never trimmed and therefore started producing cones. The third one is almost a miracle to me. Closest Abies koreana that I'm aware of is at least a few hundred meters away from where I found it. I'm very glad I dug it out too because A. koreana was also on my wanted list. :)

I'm very proud of the group's ID's. I've thanked everyone. Even though my pictures were bad and the ID's weren't totally accurate they pointed me in the right direction. I've handled the Euonymus and it is definately a Manhattan. I'd have to travel to Ohio in order to obtain higher res photos. My only dissappointment is on picture number 3. I realIze that my crappy photos contribute to my dissappointment. Number 3 just doesn't look like a Weigela.
