Ideal Planting Area

Aglaonema simplex is best suited for the moist foreground or midground zones of paludariums and semi-aquatic setups. While it is sometimes used in aquariums, this species is not a true aquatic plant and should not be kept fully submerged for extended periods, as this can lead to rhizome rot. Its modest height, reaching up to 20–40 cm (7.87–15.75 inches), adds depth and texture to planted environments without overshadowing other species. It thrives when its roots are kept moist and its foliage exposed to air. Ensure that neighboring plants do not block the light, as this species prefers moderate lighting conditions to maintain its vibrant foliage.

Propagation Methods

Propagating Aglaonema simplex is straightforward, primarily achieved through its rhizome. When planting, avoid burying the rhizome entirely under the substrate, as this can lead to rot. Instead, place it on top of the substrate and cover it lightly with sand. Over time, the rhizome will produce new shoots that can be divided and replanted. To propagate, gently split the rhizome into smaller sections, ensuring each piece has a few leaves and roots. These sections can then be placed in the aquarium, where they will gradually establish themselves and grow.

Difficulty Level

Aglaonema simplex is considered an easy-to-care-for plant in suitable environments such as paludariums, ripariums, or moist marginal zones. While sometimes placed in aquariums, it is not recommended for long-term full submersion, as this may cause rhizome rot or decline. The plant tolerates a wide pH range (6–8) and prefers moderate lighting. Occasional fertilization supports its slow but steady growth. Thanks to its low maintenance needs and environmental adaptability, it is suitable for both beginners and experienced hobbyists working with semi-aquatic setups.

Short Description

Also known as the Malayan Sword, Aglaonema simplex originates from South Asia, including Malaysia, the Philippines, and Borneo. It is not a true aquatic plant and does not tolerate full submersion for extended periods. While occasionally used in aquariums, it is better suited for paludariums, ripariums, and moist marginal zones, where its roots remain wet and foliage exposed to air. This plant features broad, green leaves that add a naturalistic look to any semi-aquatic or shallow water setup. Its slow growth rate ensures minimal maintenance, and it thrives best in sandy substrates where the rhizome is kept above the surface to prevent rot.
