Lobelia kalmii aka Kalm's Lobelia

Lobelia kalmii belongs to the bellflower family, Campanulaceae. It is a perennial, a plant that lives for years. One common name is Ontario lobelia. Its home range spans subarctic North America and the northern United States. Kew places it in the temperate biome, a broad climate zone. Chicago Botanic Garden lists it as native to the Midwest. The Royal Horticultural Society does not list it as native to Britain or Ireland. These sources place its roots in North America, not Europe.

The plant grows upright and comes back each year. These facts give a broad sense of its garden form. The supplied records do not state its full-grown height or width. They give no account of this species' leaves or stems. The RHS page describes the genus, a wider plant group. That account does not show which traits this species has. We need more evidence about this species to describe its leaves.

Chicago Botanic Garden states that the flowers are blue. It lists bloom times from July through October. These months span summer and autumn. The entry does not say if blooms last without a break. Nor does it give their size or scent. The sources do not describe the fruit or seeds. They do not name the insects or other animals that pollinate it, or move pollen between flowers.

Chicago Botanic Garden lists full sun and moist soil for growth. These are the clearest growing needs in the supplied records. It lists hardiness in USDA zones 3 through 5. The entry gives no guide to soil texture or pH. It does not say when or how much to water. Nor does it say how well the plant copes with drought. The source supports moist soil, but gives no set water amount. The supplied species records give no UK hardiness rating.

Chicago Botanic Garden lists the plant for beds and borders. Its upright form and blue blooms suit that stated role. The sources do not rate its growth speed or ease of care. They name no pests, diseases, or other repeated garden problems. They give no evidence of edible parts or uses as medicine. They do not assess its safety for people or pets. A lack of facts on toxicity does not prove safety.
