General Description
Bacopa caroliniana, also known as the Lemon Bacopa, is a plant originating from the southeastern United States, commonly found in marshes both submerged and emerged. This aquatic stem plant features ovate leaves that emit a pleasant lemon scent when crushed. It grows relatively slowly, requiring ample light (at least 0.5 watts per liter) and benefits from micro and macronutrient fertilization. In high light conditions with low nitrate levels, the plant takes on a bronze-brownish hue; decreasing phosphate levels can induce a pinkish tint. In temperate climates, it can also thrive when grown emerged, showcasing a creeping habit, hairy stalks, and distinctive purple flowers.
Aquarium Suitability and Demands
Bacopa caroliniana is frequently available commercially, making it a popular choice among aquarists. This plant is classified as easy to care for in aquariums, provided it receives sufficient lighting and periodic nutrient supplements. When planted in terracing or grouped arrangements, especially in the midground or background of the tank, it enhances the overall aquascape, providing a visually appealing resting point for other aquatic flora.
Aquascaping & Usage
Within an aquarium setting, Bacopa caroliniana thrives as a background or midground plant, suitable for creating terracing effects or Dutch-style street layouts. Its slender stems can reach heights of 20-60cm and widths of 3-6cm, offering dimension and structure to aquatic landscapes.
Propagation
Propagation of Bacopa caroliniana is straightforward, primarily achieved through cuttings of the top or lateral shoots, which can be replanted to propagate new growth. Additionally, the plant forms runners from its stem bases, simplifying the propagation process by allowing these runners to be trimmed and replanted, facilitating the spread of the plant within the aquarium setting.
Habitat and Distribution
Natively found in North America, specifically in the southern and central regions of the United States, as well as Mexico, Bacopa caroliniana thrives in marshy environments. Its adaptability to both submerged and emersed growth makes it a versatile plant that can flourish in various aquatic habitats, adding aesthetic value to aquatic ecosystems.
