Ducher is a china rose that thrives in the heat of the South. The blooms start off this lemony-white color and then gradually turn pure white. They also have a light citrus smell that is very pleasant. When the weather is very hot, the blooms typically are smaller and crisp quickly in the sun. Now that the weather is starting to get cooler, they blooms aren't crisping as badly.
This is a picture of the bush a few weeks ago at the peak of summer. As you can see, it's quite healthy and bushy. There is no blackspot at all and the form is lush. This is a plant that truly loves my Louisiana climate. I don't spray at all and it still keeps on thriving. I think this would make a perfect landscape rose here.
Here is a picture of the plant at its peak in the spring. It looks similar in the Fall once the temperatures cool down. I consider this to be a white "Knockout." The pleasing shape and growth would make this a nice shrub even if it didn't bloom. The fragrant, white buds are just "lagniappe."
