It really is very difficult to see anything clearly in the picture as there are so many plants there. I think I can see a Rubus (ie blackberry or raspberry) when I enlarge the photo but a picture showing only the plant you are referring to would help a lot.

Looks like a Sedum, maybe S. rupestre. If so, a full sun plant, creeping ground cover that shouldn't need any watering except in case of serious drought, hardy to Z4. http://davesgarden.com/guides/pf/go/3294/

Hi again! Beautiful picture! :) TY! I'm using my phone to do this. I just tried to post a pic straight by taking the picture and it just goes back to the main page. Whenever I try to either take a pic or upload, I get the 4 options to use camera, camcorder, voice recorder or documents. My pics r in the documents and I've tried to just post from the camera, but it goes straight back to the main question pg, like I haven't done anything,!! I'm wondering if I need to download something else? It's not letting me to the chrome extension,! I'll report now. Sooo, the vines are ALL OVER, but now the bottom little "clusters", kind of like a giant blackberry & the bottom round parts, are turning black one by one! The tops r still green w purple tip. Doesn't smell like anything I know! My twitter handle is @DrBrittGalb & I've posted pics on there for help!! & IG, drbrittgalandlunablupom (drbrittandlunablu) Im new to it, so I'm not sure which name, lol. Thank u SOO MUCH for ur help,! They are taking over everything now so I REALLY need to figure out if I should move them or not! Can't get to other blooming plants! Ttys! Britt

Don't know if the plant will make it. While removing the diseased parts I saw that the main stem at ground level is split open with some tan colored substance coming out. So maybe it is hanging on a thread at this point. Our weather has been excessively swampy which is normal for us in mid to late July. I've a feeling that had a negative impact on it. We do have pumpkin growers in our region but I imagine their fields have better circulation than us. We are living at the edge of the woods and the air here is often quite still and humid. That doesn't help. I'm keeping a close eye on it and hoping it can survive long enough to pick our veggie. This made me think about the summer our neighbors gave us a tomato plant and it gave us one solitary tomato! Lol
