American bellflower

Campanula americana | Rating: 0 votes | Print / Pdf

Surveying its surroundings from on high, campanula americana or the American tall bellflower stands out in more ways than one. Both tall and incredibly attractive, this plant features upright stems on which ovate, toothed, dark green leaves and stunning purple-blue flowers are displayed. Despite the common name of the plant, the flowers resemble stars in shape and certainly light up a garden design with ease. American tall bellflower likes loamy to sandy soils that are kept moist and will grow in sunny to fully shaded areas, though ideally it should be grown in partial shade. This plant is attractive to birds and butterflies and looks utterly enchanting in a woodland garden.
