I have been very pleased with this plant in its second year in the Denver area. The flowers were a nice blue and this was one of the longest blooming plants in my garden. It takes no care--you don't even have to deadhead them as the flowers don't die. The plants get a nice size. The foliage is okay--I like the texture and contrast-- but you may want to plant a shorter plant in front to hide it.
