Wow, after doing more research and a search on the forum about trilliums, I feel awful that I dislike them so much! It seems like some really treasure them. My husband's cousin even offered to come and take them. I will definitely come here first before I start complaining about what I have in my garden. My flower bed is overtaken with some plants that, again, I have no idea what they are. I'll be back with more pictures!

I don't think the first one is Vinca, although that's what I thought it was, too, at first. The edges of the leaves are serrated, and Vinca doesn't have serrations. Also, the stems are too thick. 2. Agree, Virginia creeper 3. Agree, weedy grass 4. Agree, Mulberry 5. no idea 6. can't tell, not sure what I'm supposed to be looking at 7. no idea 8. pokeweed 9. definitely some sort of wild rose, looks to be the invasive, suckering kind rose shoot goldenrod rose of sharon violet

The heavy clay soil part doesn't sound correct for this species, but everything else does, like it growing right next to a Black Jack Oak, growing on a hill, both of which point to a dry well drained growing site. My best guess is you have Sand Post Oak (Quercus margarettae) based on the leaf lobing and general shape or this could be just an unusual leaf from a standard Post Oak (Q. stellata). If you can see a small twig(1st or 2nd year twig, so the outer most part of a branch) on this tree look to see if it's hairy or smooth. If it's hairy then you have Post Oak, if it's smooth then you have Sand Post Oak. The Ozarks(Southern MO, Northern AR, SouthEast KS, Eastern OK) and much of the Cross Timbers(North Central TX, Central OK, and Central KS) are dominated by almost pure stands of Post Oak with Black Jack Oak mixed in, in the driest most nutrient deficient soils. The soil in all of these areas where Black Jack Oak occurs are sandy or soils derived from sandstone. In other parts around here (Eastern KS), they grow in association with each other only on relatively dry sandy sites. When I say sandy, I'm talking about decayed sandstone which is made up of extremely tiny sand grains and sometimes the sandy part is only noticeable if you pinch some soil between your fingers and you feel the grit of the fine sand rather than the smoothness or slipperiness of clay(at least when it's moist). Also, when the soil is very dry it's still able to break apart without great effort, in contrast to more clayey soils, which can be like concrete when very dry and only breaks apart with great effort.

Hmmmmm - no scent at all? That is consistent with Peace. (Exasperating disclaimer of the reality: some people find Peace to be delightfully fragrant, but others (including me) find Peace to have no scent whatsoever. :-)) If it's Peace, you'll know soon enough as it opens. It has an ethereal beauty that is breathtaking! I believe I've read before that at least for a while after it was introduced, at rose shows it won so many blue ribbons that show hosts created a separate class just for Peace blossoms so that the rest of the hybrid tea entries wouldn't automatically lose to it! Consequently its legacy in progeny is huge. I grow two hybrid teas in my little condominium area (Fragrant Cloud and Paul Shirville). BOTH are grandchildren of Peace.
