One could check/confirm by looking for a geniculum on the petiole of those larger leaves. Homalomena would have that, Philo does not. Philo scandens can make larger leaves like these.

Hi, Looks like a Crotalaria -- maybe C. retusa ? Regards

My very first thought was a knautia, followed immediately by the thought of a scabiosa. I will be honest and say I have both and can never remember which is which. At the moment, whichever one it is, is blooming and I think it's knautia. I think this because I've noticed this plant, which I WSed two years ago, reseeds. I've gotten store-bought scabiosas which don't seem to reseed for me, so I've concluded that this particular plant blooming in my garden now is the knautia, and it looks very like your photo. If yours is knautia, and if mine is knautia, lol, I wouldn't say it's invasive. It's only my second year with it, and I've got a few new reseeded plants, but I like the reseeding and don't find it alarming... yet. But again, only my second year so maybe others will know more. :) Dee

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. :)
