Imagine a petite petunia with intensely-colored, trumpet-shaped blossoms in shades such as magenta, violet, or copper. Flowers smother the slightly fuzzy, gray-green leaves from late spring until the first hard frost. Prolific flowering means that new flowers quickly replace those damaged by hail, a major asset in our area. Mature plants reach about eighteen inches in width and are less than a foot high. A relative newcomer on the garden scene, Calibrachoa has already gained a place of honor among annual flowers.
