Campanula cochleariifolia, commonly known as Bellflower, is a beautiful plant that offers a burst of vibrant blue flowers during the summer months. This compact, herbaceous perennial is a popular choice for gardeners who are looking to add color and charm to their outdoor spaces.
One notable feature of the Bellflower is its heart-shaped leaves. The leaf base is cordate, giving it a distinct and attractive appearance. The leaf margin is serrate, with small teeth along the edges, adding texture to the overall foliage. The leaves are ovate in shape, resembling an egg, and have a glossy surface, giving them a shiny, healthy look.
In terms of size, the Bellflower typically grows to a height of 10 to 20 cm, making it ideal for planting in borders or rock gardens.

One key advantage of the Bellflower is its hardiness. It is well-suited for USDA zones 5 and 6, meaning it can withstand cold winters without much difficulty. This makes it a reliable choice for gardeners in regions with cooler climates.
In terms of soil fertility, the Bellflower prefers well-drained soil and does not thrive in poor soils. It benefits from soil with a neutral pH level (6.5 - 7.5) and can also tolerate slightly alkaline conditions (pH above 7.5).
Another noteworthy characteristic of the Bellflower is its non-toxic nature. While it is always important to exercise caution around plants, especially if you have pets or small children, the Bellflower poses little to no risk if consumed.
Overall, the Bellflower is a delightful plant that brings beauty and charm to any garden. With its heart-shaped leaves, vibrant blue flowers, and compact structure, it is a true gem.
