donnabaskets, I must not have explained very well. The brown spots are only on the bottom of the leaves and the stems, and they are actually bumps. When I rub them I have a brown powdery substance on them. All of the brown spots are almost perfect circles. It is definitely not burn from heat as I have seen that on many other plants before. These same plants have made it through 2 previous summers here in Dallas. I don't know why. I know they aren't supposed to, but they have with no trouble at all from the heat. They are under a tree so that probably helps. I don't want to pull them up because I was happy I had found a plant that would live all year long. I spend so much money on plants that it helps to find some that last forever. They don't bloom all year of course (only in the spring), but they live and look good as little bushes. I don't even have to do anything to protect them in the winter and they are on the north side of my house! If you have any other thoughts on what this might be please let me know. I would really like to save them.

It looks like the cats of the common buckeye butterfly! I am very jealous. I have only seen an adult here once, but have host plants planted just in case one ever shows up to lay eggs. Link with more info. http://www.butterfliesandmoths.org/species/Junonia-coenia

Al, These plants were uprooted and subsequently planted, as I mentioned in the original post. I had to put them in soil as soon as possible and I doubt anyone, even an experienced gardener like yourself, could have avoided the stress of transplant unless they dug out a block of dirt when moving them. These were growing in a gravel driveway and were going to be sprayed with herbicide. I saw the opportunity to save a few. That is all. I find your comment very condescending.

It would be helpful if wr knew the identity of the weed. A picture would help. But, I'll tell you right now that it very unlikely that an herbicide exists that you can apply to the whole area in hopes of killing only that vine.
