Lobelia erinus is naturally found from America to Africa. It grows in most well drained moderately fertile moist sandy to light clay loams and tolerates chalky soils with a pH range from 5.6 to 7.6 and is frost and drought tender. It is moderately deer resistant.

Edging Lobelia is grown for its spreading foliage and flowers. It is used as an edging plant in small or cottage gardens or mass planted as a temporary ground cover. It is also used in hanging baskets or rockeries as a spill-over, establishing in one season. It has long lasting flowers that give an excellent show and grows in a wide range of climate zones.
