General Description
Hygrophila polysperma 'Ceylon', a narrow-leaved variety, has been cultivated since 1977, initially known as H. polysperma 'red'. Originating from Sri Lanka, this fast-growing plant exhibits a coppery hue under sufficient iron levels and is easily propagated through cuttings. Its growth rate can lead to nutrient imbalances, requiring diligent monitoring and fertilization adjustments.
Aquarium Suitability
Considered very easy to care for, H. polysperma 'Ceylon' thrives in various conditions, including low-light environments without CO2 supplementation. However, rapid growth may necessitate maintenance efforts to prevent spindly growth. It is ideal for the middle to background of aquariums and can be planted in the substrate or grown emersed if provided with ample water and nutrients.
Demands and Hardiness
In aquariums, H. polysperma 'Ceylon' can tolerate a wide range of water conditions, with a temperature range of 22-28°C and a tolerance level of 4-35°C. It can adapt to pH levels between 5 to 8 and requires moderate levels of nitrate, phosphate, and potassium. CO2 levels between 5-40mg/l are beneficial for its growth.
Aquascaping & Usage
This plant's long, narrow leaves serve as an attractive background element in aquascaping due to their contrasting appearance against other species. The lateral or top shoots can be trimmed and replanted in the substrate to manage its exorbitant growth. Regular maintenance is crucial to keeping H. polysperma 'Ceylon' visually appealing.
Propagation
Propagation of H. polysperma 'Ceylon' is straightforward and involves cutting and replanting its lateral shoots. The plant's rapid growth and lateral shoot production make it easy to propagate and distribute in the aquarium.
Habitat and Distribution
Found in Sri Lanka, H. polysperma 'Ceylon' is a variant of the broader species Hygrophila polysperma. Its native habitat and distribution are rooted in the aquatic environments of Sri Lanka, making it well-suited for aquarium cultivation.
