What a stunner! The cardinal flower (Lobelia cardinalis) adds is a cheerful addition to the garden. The wetland plant has fiery red flowers. An easy plant that thrives anywhere. The aquatic plant is a waterside and marsh plant. We can plant the plant along the edge (bank) of our pond. Or we can plant the plant up to 15 cm deep in the pond. Plant Lobelia in the spring. The flower blossoms in the summer.
We prune the plant slightly to shape it with a pruning shear. We remove old leaves and dirt. To encourage good growth, we add minerals to the pond water and ensure that the water's hardness level (pH value and calcium to magnesium ratio) is maintained. We make sure to plant Lobelia in a sunny spot.
