If the leaves are actually quite small, possibly Lobelia erinus.

hello, can someone on this list please inform me as to how I can get a grand duke cutting? I live in Oregon and would love to have some cuttings of the plant with the flower on the very top of the thread. I am sure this is the jasmine grand duke of Tuscany. I would be happy to mail some cuttings of what I have. I had 3 exotic types of Jasmine in my home: Arabian Jasmine, Maid of Orleans Jasmine, and Grand Duke Supreme jasmine (this one is very small so I could give cuttings on this one at a later time). Or i can pay for your cuttings of the picture above on this thread. Please contact me at: rupalpai@gmail.com to communicate with me. I would really love a cutting and would like to know how to get one. Thanks much.

From the look of your photos, especially the last one, it seems as if the original pink rose is being overtaken by rootstock suckers. All of those longer canes look like Dr. Huey to me. (Dr Huey is a once-blooming climbing rose that blooms on canes produced the previous year, so first year canes get very long and they don't terminate with a flower bud.) It may be too late, since the rootstock suckers have such a good head start, but there's no harm in trying to reverse Dr. Huey's onslaught. Follow each cane to its base to see where it originates on the plant. If it is below the bud union (the swollen, knobby area where the pink rose canes come from) tear the cane off completely. If you cut them, it leaves behind tissue that will produce more new rootstock canes, and you don't want that. You can cut the rootstock suckers down a bit to make it easier to see the base of the plant, but don't rely on cutting to solve the problem. I'm sorry that I can't help with the ID of your pink rose.

Still hard to tell, but I can see the tail, and it's not a rattlesnake. http://www.oksnakes.org has a list of species. The non-venomous Diamond-backed Watersnake might be it, based on color. There is an outside chance it might be a cottonmouth - if they are known to live in Norman, OK. But I'd need to see the head shape, too.
