Blue Bellflower (Campanula sp.) is planted for its blue bell shaped flowers and attractive green foliage. Native to different parts of Europe. Generally this plant declines after a few years of Kansas climate but worth a try in perfect soils in well-tended part-shade gardens. Preferring northern climates, lack of moisture, alkaline soils, and competition with weeds seem to be an issue.
