Campanula collina, which is commonly known as sage-leaved bellflower proves that it doesn’t have to be a struggle to enjoy pretty plants in your garden. With violet-blue, bell-shaped flowers suspended on slender, upright stems above ovate, toothed foliage, this plant is exceptionally pretty and also easy to grow. Sage-leaved bellflower appreciates average fertile soils that are moist and well-drained. It will grow in sunny spots as well as partial shade and is brilliant for creating bright, bold borders. If you want some colour for your patio grow this plant in a large container or alternatively allow the sumptuous flowers to reign supreme in a regal rock garden.
