I used to live in Georgetown so know how hot it gets. I think Mike's suggestion of arbors is excellent. You could also consider a couple of crepe myrtle trees - White Natchez crepe myrtle is a tree that can take alot of punishment and survive well and bloom in the summer. The Natchez has a really pretty arching form and can give some height and interest to the wall and perhaps a bit of shade to the roses. In back of my horse barn in an area with all day hot sun, I have crepe myrtles and old garden roses [Maman Cochet, Mrs. BR Cant, Mon. Tillier, Mme. Berkeley, Georgetown Tea] planted together - the effect is beautiful. I have differing colors of the crepe myrtles - lavender [here is where you could include your lavender color], hot pink, light pink, white, red - really is striking in the hot summer when the roses are resting. I have also found that it really is true that mulching is important. I mulch my roses with horse compost then topdress with wood mulch from Home Depot. The roses thrive - the ones I didnt mulch dont look nearly as good. My suggestion would be to plant old garden roses first - and I also highly recommend the Antique Rose Emporium and Chamblees. I was just at ARE - bought several of the Pioneer roses that are supposed to be really tough. Also, I would like to recommend the Buck roses. Carefree Beauty is a good one. There are many other good ones - Eutin is a red that has literally hundreds of buds on it - really an eyecatcher. The noisettes - and I adore Crepuscule! - are very hardy. The ARE had a store in San Antonio, now closed, but I would call P.K. at the Independence store - tell her your growing conditions, and let her recommend. Get their color catalog and look that over. I think the really important thing for first year roses is to mulch and water. I did that with my above mentioned bed - now I never water them and they are fabulous. If you dont have much experience with roses, you will succeed with the old gardens - then branch out to the hybrid teas if you like. If you built an arbor, you might have some luck growing a couple of the Austin roses under it where they can get a bit of shade. A couple of tough reds are Cadenza and Cameron Bohls. I have both and love them. Dont forget about the Lady Banksia rose - both white and creamy yellow. They are marvelous in the spring. New Dawn should do well also. From what I recall of soil in your area - be sure and dig a big hole and incorporate good soil with the native soil. I have also heard - bought some, going to try it next time I plant - that a cupful of shale, which holds then releases water, is good to put in the hole of roses growing in dry hot areas. Good luck! Love the limestone on your house....

Thats a good question, I found a place online where I can get a tall box (14x14x49) If the plant could fit at four feet. I saw one on another site that was 10x10x60 which would be ok for height as long as the plant isn't too bushy and could have its branches fit. If you wouldn't mind the trouble you could buy the plant for me now while they have them and I could order the special box online and just have it sent to you for shipping the plant if you give me your address. It's up to you though, I hate to ask all this because I know its a pain but I would so very much appreciate it. If you are willing to do this send me an email so that your info isn't posted for everyone on the forum. My email is Aslan89@gmail.com and thats asLan not asian as some people think haha.

Im not sure why you are worried about 15 degrees? depending on your properties exact location near the water down there you could likely grow anything that is commonly grown in orlando fl. According to my map that area has only been anywhere near or below 15 degrees 1 time in the last 108 years. and that was 12 degrees in 1899. I dont know about you but, I dont plan for the once in a lifetime freeze otherwise I wouldnt have any palms growing. the absolutely deadly (to florida and texas) freeze of 1989 sent the official temp to 18 in brownsville and based on the remaining palms of the area if you were nearer the water you stayed above probably 25-28 since there are some older less hardy palms still around. id pin the min yearly low at abou 28 with water making that temp rise to at least 32-35.... I dont think this is too optomistic in looking at the palms growing down that way.

I have had good luck with Morning glory vine. You just soak the seeds for 24 hours or so and then plant and water and while it can seem like it takes a bit to get them going, once they start to take-off there is NO stopping them. Plus, you get the beauty of the gorgeous, heart-shaped leaves and the beautiful morning flowers! I have planted some at the base of each of my back patio posts and will attach fishing line to each pole for the vine to twine around on. Mine have just now really started putting on some noticeable growth and it is soon going to be time to train them up! Good luck with whatever you choose!
