Hygrophila Corymbosa Siamensis/Stricta
Hygrophila Corymbosa Siamensis/Stricta is the classic large-form expression of the corymbosa Siamensis group — one of the most widely grown and universally reliable background plants in the entire aquarium hobby. Producing bold, broad leaves on thick, sturdy upright stems, this plant is immediately recognizable as one of the most dependable and visually substantial background plants available for any planted aquarium style.
Care tip: Hygrophila Corymbosa Siamensis/Stricta grows best in moderate lighting with CO₂ optional. Maintain temperatures of 72–82°F and pH 6.5–7.5. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 10 to 20 inches, this is a large, vigorous background plant that fills background zones quickly and reliably. Regular trimming maintains a manageable height and produces increasingly bushy, full growth. Unlike the more compact 53B cultivar, the standard Siamensis/Stricta form produces larger, bolder leaves that create a more substantial and dramatic background presence in larger aquariums.
This easy plant grows well under medium lighting with CO₂ optional. Temperatures between 72 and 82°F and a pH of 6.5 to 7.5 provide comfortable conditions. Regular fertilization maintains vigorous growth and the full, healthy leaf production that makes this plant such a reliable background staple. Its low CO₂ requirements make it accessible in virtually any planted tank setup.
In the aquascape, Hygrophila Corymbosa Siamensis/Stricta provides bold, reliable background structure whose large broad leaves create substantial visual mass in the rear zones of the layout. It is most impressive in larger aquariums where its generous leaf size can be fully appreciated. In low-tech setups it is frequently the most dependable and consistently healthy large background plant in the composition.
Hygrophila Corymbosa Siamensis/Stricta is a timeless classic of the planted aquarium background — bold, reliable, adaptable, and always visually impactful. Its proven track record across decades of planted aquarium keeping makes it one of the most trusted background plants in the hobby.
