Bacopa

Bacopa is a genus of aquatic plants in the family Plantaginaceae. These plants are native to tropical and subtropical regions worldwide, and they are commonly known as water hyssops.

Bacopa plants have a creeping or trailing growth habit, with long, narrow leaves that are arranged oppositely along the stem. They produce small, delicate flowers that are typically white or pale blue in color. Bacopa plants are commonly found in freshwater habitats such as ponds, lakes, and slow-moving streams.

In the aquarium hobby, Bacopa plants are highly valued for their attractive appearance and their ease of care. They are often used as background or midground plants, and their long, trailing stems make them ideal for creating a natural, flowing effect. Bacopa plants are relatively tolerant of a wide range of water parameters, but they prefer moderate to high light intensity and nutrient-rich water. They can be propagated by stem cuttings, which can be rooted in the substrate or floated on the water surface until they develop roots. Some popular species of Bacopa in the aquarium hobby include Bacopa caroliniana, Bacopa monnieri, and Bacopa australis.
