Bacopa caroliniana is a hardy stem plant with thick, rounded leaves and a rich green colour. Its upright, steady growth makes it a popular choice for the midground or background, where it adds structure without overpowering the layout.

Planted in groups, it grows at a moderate pace and is very tolerant of a wide range of conditions. Moderate lighting is sufficient, though stronger light can encourage more compact growth. CO₂ is optional, making it well suited to lower-tech aquariums. Regular trimming helps maintain shape and encourages bushier growth, while cuttings can be replanted to fill out the layout over time.
