Bacopa caroliniana: Origin, Water Conditions, and Lighting Needs

Bacopa caroliniana, commonly known as blue water hyssop or lemon bacopa, is an aquatic plant native to the southeastern United States, particularly found in marshy areas from Maryland to Texas, including Florida. It has also been reported in South Korea and Mexico, indicating a broad distribution in wetland habitats123.

Origin

• Native Range: Southeastern United States (Maryland to Texas) and parts of Mexico.
• Habitat: Commonly grows in freshwater marshes, along shorelines, and in disturbed wetlands12.

Water Conditions

• Water Type: Prefers freshwater but can tolerate slightly brackish conditions.
• Growth Conditions: Thrives in submerged or semi-submerged environments. It can adapt well to flooding and is often found in bogs and along the edges of ponds123.
• Nutrient Requirements: Prefers a clean, nutrient-rich environment for optimal growth. Regular fertilization can enhance health and color24.

Lighting Needs

• Light Requirements: Bacopa caroliniana grows best under moderate to high light conditions. While it can survive in low-light environments, brighter light promotes healthier growth and vibrant leaf coloration26.
• Color Variation: Under high light levels, the leaves may turn bronze or even red, while low phosphorus levels can lead to pinkish hues26.
