General Description
Cabomba caroliniana var. caroliniana, commonly known as Carolina fanwort, is a popular aquatic plant often found in aquarium trade. Originating from lakes, ponds, and rivers in the Americas, this plant is known for its fast spread in nature and can become invasive, such as in Australia where it is considered a Weed of National Significance. When cultivated in optimal conditions, it produces ovate-diamond-shaped floating leaves and white flowers on stalks that can grow to the surface of a large aquarium when trimmed drastically.
Aquarium Suitability
Carolina fanwort is suitable for aquariums and is frequently available commercially. It is categorized as a medium difficulty plant and can thrive in environments with medium to high light levels and a temperature range of 20-25°C. While the pH and water hardness do not significantly impact its growth, micronutrients can benefit its development. This plant does not require additional CO2 supply but can benefit from it to enhance growth.
Demands and Hardiness
Carolina fanwort grows very fast and can be used as a background or midground plant in aquariums. It is fine-leaved and can withstand somewhat colder temperatures, although care should be taken with extreme cold. Maintaining nitrate levels can influence the plant's hue, with lower nitrate levels leading to a darker green or brown color, especially under intense lighting.
Aquascaping & Usage
In aquascaping, Cabomba caroliniana var. caroliniana serves as a welcome contrast to other plants with its lime green color and finely forked leaves. Its ability to grow quickly and fill out space makes it ideal for creating lush backgrounds or adding texture to the midground of aquarium setups.
Propagation
Propagation of Carolina fanwort can be done through cuttings, splitting, or cutting off daughter plants. However, it is important to note that the lower part of cut stems may require time to grow lateral shoots, as this process is less common in this plant.
Habitat and Distribution
This plant is native to the Eastern USA and Southeastern South America. It belongs to the family Cabombaceae and typically grows in lakes, ponds, and slow-moving rivers. Carolina fanwort thrives in aquatic environments with a pH range of 5-7 and can tolerate temperatures between 4-27°C.
