General Description
Species or varieties of the genus Oldenlandia, comprising narrow-leaved plants, have gained popularity in recent years as aquatic plants for aquariums. Belonging to the Rubiaceae family, similar to the oval-leaved Hedyotis salzmannii from South America, they are typically imported from Asian tropics.
Aquarium Suitability
Oldenlandia species are considered suitable for aquariums, with a medium level of difficulty in maintenance. They thrive in environments with medium to high light levels and specific water conditions (see table) typical of tropical fish tanks.
Demands and Hardiness
Oldenlandia plants require carbon dioxide levels between 20-40mg/l and a pH range of 5-7. They can tolerate temperatures between 23-28°C and a tolerance range of 20-30°C. Additionally, they prefer a moderate to high carbonate hardness and nutrient levels within specified ranges.
Aquascaping & Usage
As midground plants, Oldenlandia species with their narrow stem structure and small width of 4-6cm are ideal for enhancing the visual appeal of aquarium layouts. Their emersed growth characteristic can add an interesting dimension to aquascaping designs.
Propagation
Propagation of Oldenlandia plants can be achieved through seeds or cuttings, making them relatively easy to propagate and maintain in aquarium settings.
Habitat and Distribution
Although specific details about the habitat and distribution of Oldenlandia species are not provided, their natural habitat is likely in tropical regions, especially in Asia, where they are commonly found.
