It's wonderful to see that so many of the top 50 plants have red or orange blooms. I've always been biased against xeriscaping because it looks so boring. The xeric gardens in my county tend to have flowers of only two colors: grayish-mauve and mauvish-gray.
I have alot of these plants (over 1/2)!
I have a real xeri bed...gets no irrigation and sits between 2 driveways. I can grow blackfoot daisies that bed..also have colors other than grey!
