Clarkia concinna is a species of wildflower in the Onagraceae (Evening Primrose) family known as Red Ribbons. It is endemic to California, where it can be found in the northern Coast Ranges from Santa Clara County to Humboldt County, and in the Sierra foothills. This is an annual plant with erect, herbaceous stems. The distinctive flowers have four looping sepals of red or dark pink which look like loops of silk ribbon. The longer, pink petals have three lobes which are usually streaked with white.
