Campanula garganica aka Adriatic Bellflower

Campanula garganica is known as the Adriatic bellflower. It belongs to the bellflower family, Campanulaceae. Its native range covers southeast Italy and western Greece. It grows in a temperate climate. Kew lists its form as a perennial or subshrub. The RHS treats garden plants as herbaceous perennials. This species is not native to Britain or Ireland.

This small plant forms low cushions and spreading mats. It reaches about 0.33 feet [0.1 metres] in height. Its spread ranges from 0.33–1.64 feet [0.1–0.5 metres]. Plants reach their full size within two to five years. The small leaves have a heart-shaped outline. They are deciduous, so the plant does not keep them year-round. Lilac-blue flowers cover the leafy cushions in summer. Each bloom has a star-shaped form. The low foliage and summer flowers suit the front of beds.

Choose a sunny spot with soil that drains well. The RHS also lists partial shade as suitable. It prefers moist soil without poor drainage. Suitable soils include chalk, loam, and sand. It tolerates acid, neutral, and alkaline conditions. Plants can grow in exposed or sheltered sites. The RHS gives it a UK hardiness rating of H5. Plants For A Future lists USDA zones 4–8. These ratings describe hardiness under different regional systems.

Use it in rock gardens, gravel beds, or containers. Its low mats also suit edging and ground cover. The RHS suggests planting beneath roses and shrubs. It lists cottage gardens, courtyards, and wildlife gardens among suitable settings. Plants For A Future also suggests dappled woodland shade and wall planting. No pruning is needed. Raise new plants from seed or softwood cuttings. Slugs and snails may damage the plant. Powdery mildew can also affect it. These are possible problems rather than signs of certain failure.

Plants For A Future lists both leaves and flowers as edible. Eat either part raw or cooked. The small leaves have a mild taste and suit salads. The flowers have a light sweetness.
