The lobelia cardinalis is a stem plant from North America. The fleshy stems grow very slowly and only reach heights of 10-20 cm underwater. It is often used in the "Dutch aquarium" planting style, where the plants are arranged strictly in large, dense groups and are grown to give the impression of a botanical garden.

It is a slow-growing species with minimal requirements regarding water parameters, substrate, and water temperature.
