Evergreen in zone 9b.

I own several tea roses and this one is in my top three. It blooms constantly and I can always cut a bouquet for my table. The colors are beautiful - so many different ones on the same flower. The flower form is quite pretty for a tea rose. No disease ever, no insect problems and extremely carefree. No problem blooming in 100 degree weather in the summer, and blooms at Christmas time here in Houston. I don't understand why this rose isn't more popular. It is the perfect rosebush.
