Add exotic flair to your aquarium with the African Onion Plant (Crinum calamistratum), a visually stunning aquatic plant known for its long, curly, ribbon-like leaves and bulbous base. Native to Central Africa, this hardy plant is both ornamental and easy to care for, making it a favorite among aquarists.
Despite its name, the African Onion Plant isn’t related to true onions—its nickname comes from the rounded bulb that resembles an onion. Once established, it produces lush, dark green foliage that adds flowing motion and vertical texture to any aquascape. It's perfect for midground to background placement and works well in both low- and high-tech setups.
