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 40 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.

Planting+

Abundantly flowering cardinal flower (Lobelia cardinalis) makes a great pond plant - best planted in a pond basket. Line the basket with hessian and use special pond soil to fill it. Plant the cardinal flower in the basket and fill it up with the special soil. Cover with the edges of the hessian, or straw and a layer or gravel. Place in the pond so that the top of the basket comes to just below water level or at a maximum 15 cm deep. Add bricks underneath the basket if it's otherwise too deep. Full sun or part shade. Best time for planting is May-June.
This plant looks lovely in a border as long as it retains moisture well. A plant like this with lovely red blooms and red tinted leaves will be very conspicuous.
