General Description
Ludwigia ovalis, commonly known as Oval Ludwigia, is a relatively new species in the aquarium trade with origins in East Asia. This aquatic plant features beautiful pink-orange ovate leaves and is characterized by its low-growing stem with roundish-ovate leaves. Unlike other Ludwigia species, the leaves of L. ovalis are alternate, with one leaf per node. The plant forms lateral shoots regularly and exhibits a moderate to strong growth rate under sufficient light.
Aquarium Suitability
Ludwigia ovalis is considered suitable for aquariums, offering aquarists an easy-to-cultivate plant that is highly attractive and popular due to its unique coloration and growth pattern. Its low-growing stems make it ideal for the middle- or foreground of an aquarium, providing a striking contrast when planted against light green background plants.
Demands and Hardiness
Aquarium cultivation of L. ovalis requires moderate to strong light for optimal growth. While not mandatory, CO2 injection enhances growth speed and robustness. Additionally, a micronutrient supply, especially iron, is crucial for vibrant leaf colors. The plant thrives in water conditions with a temperature range of 22-26°C, pH levels of 4.5-7, and nutrient levels within specified ranges as indicated in the provided table.
Aquascaping & Usage
The vibrant colors of Ludwiga ovalis make it an excellent choice for providing colorful accents in aquascapes. Its suitability as a midground plant allows for creative design options in aquascaping, contributing to visually appealing underwater landscapes.
Propagation
Propagation of Ludwigia ovalis is relatively easy and follows the typical method for stem plants - simply cut off lateral or top shoots and replant them in the substrate. This straightforward propagation process makes it a convenient choice for aquarists looking to expand their plant population in the aquarium.
Habitat and Distribution
In its natural habitat, L. ovalis is found in East Asia, specifically in regions that include China, Taiwan, Korea, and certain parts of Japan. It thrives in cooler waters or very moist-wet soil conditions. The plant's growth habit in the wild is creeping, showcasing its adaptability to various aquatic environments within its native range.
