General Description
Hygrophila corymbosa 'Siamensis' is a robust aquatic plant, belonging to the Acanthaceae family and the Hygrophila genus. It is a fast-growing stem plant with a versatile nature that thrives in Southeast Asia. The plant is known for its adaptability to varying environmental conditions and its ease of cultivation, making it a popular choice among aquarium enthusiasts.
Aquarium Suitability
This plant is highly suitable for aquariums, thriving in most tank setups except in very small or poorly lit tanks. It has moderate demands concerning lighting and nutrient supply and can tolerate a wide range of water parameters, including hardness and temperature. However, high light intensity in combination with insufficient iron supply may lead to symptoms of iron deficiency, such as green leaf nerves in yellowish leaf tissue.
Demands and Hardiness
Hygrophila corymbosa 'Siamensis' is rated as very easy to care for in aquarium settings and is suitable for both beginners and experienced aquarists. It grows best in medium to high light conditions and benefits from a nutrient-rich environment. Regular trimming is necessary as it is a fast grower. Propagation is straightforward through cuttings, where simply cutting off a shoot and replanting it can lead to new growth.
Aquascaping & Usage
With its fast growth and bushy appearance, Hygrophila corymbosa 'Siamensis' is ideal as a background or midground plant in aquariums. It can also be used in semi-emersed setups for open tanks or arranged in a "Dutch style" street planting. The plant's striking appearance, especially when grouped in terraced stems of varying lengths, adds visual interest to aquatic landscapes.
Propagation
Propagation of Hygrophila corymbosa 'Siamensis' is easily achieved via cuttings. By snipping off a shoot and replanting it, the plant can reproduce rapidly. Trimming the top shoot can help control the growth and encourage the development of lateral shoots, resulting in a denser and more visually appealing plant arrangement.
Habitat and Distribution
This species is commonly found in various regions across Southeast Asia. It is known to thrive in diverse aquatic habitats and is particularly prevalent in areas with suitable lighting conditions and nutrient availability. Hygrophila corymbosa 'Siamensis' is considered a versatile and adaptable plant that often grows in submerged conditions, enhancing the natural aesthetics of aquatic environments.
