Lobelia cardinalis

Common Name: Cardinal Plant, Lobelia Cardinalis

The Cardinal Plant (Lobelia cardinalis) is a versatile North American species that thrives in aquariums, paludariums, and terrariums, whether grown submerged or emersed. This unique plant works beautifully as a foreground or midground accent in your freshwater aquarium, and with the right care, it can even make a striking background feature when allowed to grow taller.

 In nature, it can be found growing along streams, rivers, and waterways. With sufficient height, it can even serve well in the background. Its submerged form showcases vibrant green foliage, occasionally tinged with red-purple on the leaf undersides, though this hue is more commonly observed in its emersed form. Notably, the Cardinal Plant is renowned for its striking red flowers that bloom from its emersed growth.

To thrive, the Cardinal Plant requires moderate to high levels of lighting. Regular trimming of its tops allows for mat expansion, while proper care encourages the development of lush side shoot leaves. The addition of fertilizers can be advantageous in maintaining optimal coloration and overall plant health.
