Can be grown both submersed and immersed, so is suitable for both planted aquariums along with terrariums/paludariums.
Lobelia cardinalis is an easy to grow plant, that looks especially beautiful in a big, lush ‘Dutch Style’ planted aquarium.
In its submerged state, this plant has a lovely bright green leaf, in its emersed state, the leaves get a scarlet red underside. If the plant reaches the surface of the water, you’ll notice the leaves will start to take on their emersed form and colour and even start to grow a nice little red flower
