The blue in the 1st pic is centaura cyanus aka annual bachelor button. The tall yet to bloom appears to be cosmos bipinnatus aka annual cosmos. The red vine is lathyrus odoratus an annual sweet pea. The last pic appears to be verbena bonariensis hanging out over the side. You can indeed collect seed from these. Some of them will automatically reseed themselves if had been ground planted.

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. :)

Thanks FataMorgana. Thats the closest picture to the seed I have. When looking at the pictures, the silver edge appears shiny to me. Is that how it looks to you? On the seed I have, the edge is fuzy. Not sure if I'm just not seeing the photo correctly. I was very excited to at least see a seed that looked very simular. This has become a curiosity to me. I do plan to grow it and see what we'll get. And yes Christy, I'll collect seeds and will be glad to share :) If it is the silver edge squash, the seeds are apparently wonderful as well as the flesh. Keeping my fingers crossed. Will update as I have more info. Thanks for your help :)

Definitely ash seeds but I can't get more specific about species. Poplar seeds are downy little wisps like dandelion fuzz.....with a small seed attached.
