Adria Bellflower Overview
Campanula portenschlagiana is an evergreen perennial species, also known as the Wall Harebell or Adria Bellflower, amongst other names. It grows low to the ground with a spreading, mat-forming habit. Rounded foliage and bell-shaped blue to purple-pink blooms which measure up to 2cms in length are produced on branched stems in the summer. This is an ideal plant for sunny borders or rock gardens, originating from Southern Europe. It can often be seen growing in wall crevices where it has self-seeded. Attractive to pollinators, Campanula portenschlagiana can also be used as groundcover and will suppress weed production - but plant with care and keep growth in check, as its vigorous growth can mean that it becomes invasive. Its biggest enemy is cold, wet winters but apart from that, it happily grows in most soils and in a sunny or partially shaded position.
