a lovely plant for the aquarium and is very popular for use in formal Dutch aquariums to form the iconic “streets” seen in these tanks. In the wild, Lobelia cardinalis is quite a large plant, and this larger form is used as a marginal plant for ponds, where it produces pretty red flowers. But a smaller form has been developed in cultivation and this is a nicer aquarium plant. While Lobelia cardinalis definitely grows better with supplemental CO2 and good lighting, it can also be maintained in a less robust form in a “low tech” tank. It should be noted that in emersed form (such as when it is first purchased) the leaves are dark olive, with a maroon underside. In the submersed form seen in the aquarium, the leaves are smaller, and a bright light green.
