Campanula x haylodgensis 'Plena' | Rating: 0 votes | Print / Pdf

If you’re after a wealth of beauty to enrich your garden design, you’ll get it with campanula x haylodgensis plena, which is commonly known as plena campanula. Though the heart-shaped to rounded, toothed and dark green foliage is lovely to look at, the real highlight of this plant are the gorgeous light blue, double flowers it produces. Plena campanula likes most fertile soils as long as they have good drainage and are kept moist. It will grow in sun or partial shade and its spreading nature makes it a superb groundcover plant. It also looks magnificent sprawled leisurely within a rock garden or alternatively over the edges of a container.
