Cardinal Plant aka Cardinal Flower (Lobelia cardinalis)
Cardinal Plant is a very versatile North American plant that can be grown submerged or emersed in aquariums, palludariums, and terrariums!
Cardinal Plant (Lobelia cardinalis) is a very unusual foreground and middle ground plant for the planted freshwater aquarium. It can also be excellent in the background if grown tall enough. Its submerged form is bright green, sometimes with red-purple on the undersides of the leaves, although this red-purple coloration is more typical in its emersed form. This plant is perhaps best known for the bright red flower that grows from its emersed form.
Cardinal Plant requires moderate to high lighting. Its tops can be trimmed and replanted to increase the size of the mat. It produces side shoot leaves that will grow into new plants.

Grew my cardinal plant in a mixed planted tank and it has spread well. The red flowers in summer are a nice touch. I like how it grows tall and fills the middle ground nicely. Easy to maintain with regular trimming.

It’s a unique plant with a striking red flower. I kept it emersed and it bloomed beautifully. The submerged leaves are healthy and green. A bit slow to establish, but worth the wait.

Added this to my palludarium and it’s thriving. The plant grows steadily and adds visual interest. The red coloration on the leaves is noticeable in sunlight. Great for adding natural beauty.
