I don't know much about roses but your rose looks a lot like a white climber for sale at Edmunds roses named Cloud 10 that I was considering buying. This is Edmunds description of it: "Spring finds this modest climber heavily flushed with pure white, full and fluffy blooms that resemble English roses. As we now expect from William Radler introductions, Cloud 10 exhibits exceptionally clean, dark green, matte foliage with a high level of disease resistance to black spot, rust and mildew making it especially good for Southern regions. Reblooms throughout the season. It is hardy to Zone 5, but there it may resemble a large shrub rather than a climber - it's beautiful either way. Flower Size: 4-5". Fragrance: Not noticeable. Hybridizer: Radler, 2013"

Hi Lux, thrips can cause petal edges to brown because they suck out the sap. They LOVE lighter colored roses, particularly those with thin, papery, fragrant petals/blooms, which both Lemon Spice and Sunday Lemonade both have. Excessive heat, low humidity, intense direct sun, too much salt in the water (either naturally occurring or added fertilizers) can also do it. You can easily check for thrips by pulling open the petals and looking for small, thin insects between them. Perhaps a hand held magnifying glass or even the macro of your camera might help you see them. You may also consider if any of the other conditions mentioned above might fit the situation. Kim

I have had a Bewitched for over 10 years. It's absolutely gorgeous in Spring and late Fall. In between, it pretty much goes dormant in the heat. It does not like heat, period. Let me emphasize that - very few roses, if any, have I seen that go totally in the tank during summer heat, but Bewitched does. I agree with seil that the current climate this summer has been hot enough to burn almost every bloom. That may be all it is.

Excuse me, I should have said Glowing Peace. I had one but it died. Glowing Peace is a light-yellow rose which tends to get a pink-red blush, and can finally fade to nearly-white like the rose in the photos. The ARS rose-encyclopedia "Modern Roses XI" say it averages 45 petals. Regards, JohnReb
