Bells perennis generally blooms from early to midsummer, although when grown under ideal conditions, they have a very long flowering season and will even produce a few flowers in the middle of mild winters.
It can generally be grown in USDA Zones 4 - 8 (i.e. where minimum temperatures are above −30 °F (−34 °C)) in full sun to partial shade conditions, and requires low or no maintenance. It has no known serious insect or disease problems and can generally be grown in most well-drained soils. The plant may be propagated either by seed after the last frost, or by division after flowering.
Though invasive, the species is still considered a valuable ground cover in certain garden settings (e.g., as part of English or cottage inspired gardens, as well as spring meadows where low growth and some color is desired in parallel with minimal care and maintenance while helping to crowd out noxious weeds once established and naturalised).
Numerous single- and double-flowered varieties are in cultivation, producing flat or spherical blooms in a range of sizes (1 cm to 6 cm) and colours (red, pink & white). They are generally grown from seed as biennial bedding plants. They can also be purchased as plugs in Spring. The cultivar 'Tasso series' has gained the Royal Horticultural Society's Award of Garden Merit.
