Bellflower

Campanula is a large genus of bellflowers with about 300 species native to temperate regions of the Northern Hemisphere. Its members include annuals, biennials and perennials, so size, flower season and growing needs vary by species and named selection. ## Choosing a Campanula Garden forms range from compact plants for rock gardens to taller border perennials, and flowers can be bell-, funnel- or star-shaped. Check the species or cultivar name before choosing a site or spacing; a genus-level label does not identify one particular garden form. The [University of Wisconsin Extension overview](https://hort.extension.wisc.edu/articles/campanula-carpatica-blue-clips-white-clips/) describes the genus breadth, while the [RHS guide](https://www.rhs.org.uk/plants/campanula/specialist/growing-guide) explains how habits and needs vary among campanulas. ## Siting Many garden campanulas grow in well-drained soil in sun or light shade, while specialist alpine and tender types can need sharply drained conditions or winter protection. Treat those as examples, not rules for every member of the genus, and follow the guidance for the specific species or selection. ## Maintenance Watering, deadheading, division and winter care depend on the species and local climate. Confirm the plant's full botanical name before setting a care schedule or mature-size expectation.
