Campanula portenschlagiana
Height x Spread: 15cm x 35cm
Campanula portenschlagiana is commonly known as the Wall Bellflower, producing an evergreen mat of small rounded leaves with stunning violet-blue bell flowers during the summer.
This ankle-high European native thrives in a site with full sun or partial shade if planted in a good soil, but will not tolerate wet winters. Grow it adjacent to steps, where it can gently sprawl softening the edges or highlighted in a rockery. It tends to reseed itself around, but unwanted seedlings can be easily removed.
