Nymphaea glandulifera

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

Due to its broad leaves and potential height, it is best suited as a focal point or background plant. In smaller aquariums, it can quickly dominate the space if not strategically placed. Plant it where it will not shade out smaller, light-demanding species below it. It looks particularly striking when positioned slightly off-center in the layout.

Botanical form

Rosette

This plant develops a strong rhizome or tuber structure from which the leaves emerge. The leaves are typically broad, lobed, or arrow-shaped, offering great textural contrast. It can develop both submerged and emergent foliage depending on water depth. The stems are long and fleshy, reaching towards the light source.

Growth

Medium

Under optimal conditions with high light and CO2, its growth rate is considered fast. It will regularly send leaves toward the surface to form floating foliage. In low-tech setups, the growth is moderate but still steady. Frequent pruning can help manage the rapid development of new shoots.

Substrate

High

Column fertilization

Recommended

While it feeds heavily from the roots, it also absorbs significant nutrients through its leaves. Liquid fertilizers should contain a balanced mix of potassium, nitrogen, and phosphorus. Dosing liquid iron regularly will help maintain the intense pigmentation of the leaves. Column fertilization is especially helpful in the early stages of acclimatization.

Root fertilization

Required

Root tabs are absolutely essential for the long-term health of this heavy root-feeder. Place a nutrient capsule deep into the substrate near the base every few months. A nutrient-rich aquasoil provides an excellent foundation for its extensive root network. Without sufficient root fertilization, the plant may stunt and drop older leaves.

Trimming

Occasional

To maintain a compact submerged form, promptly trim any leaves that reach for the surface. Cut the stems as close to the base as possible to encourage bushy new growth. Remove any decaying or damaged leaves to prevent water quality degradation. If you want floating leaves, simply allow the longest stems to reach the top undisturbed.

Propagation

Runners

Propagation is typically achieved by dividing the rhizome or through side shoots. Carefully cut the rhizome with a sharp tool, ensuring each piece has a few healthy leaves. Some variations will produce adventitious plantlets on older leaves or stems. These plantlets can be separated and planted once they have developed their own roots.

Sensitivity

Moderate

This species can be sensitive to sudden changes in water parameters or temperature. It is generally not tolerant of harsh chemical treatments, such as certain algae medications. Ensure the rhizome or tuber is not fully buried, as it may rot. Herbivorous fish and snails might occasionally nibble on the tender new leaves.

Layout role

Foreground, Midground, group

This plant serves as an excellent solitary centerpiece in many aquascaping styles. Its distinct leaf shape and color break up the monotony of typical stem plant groupings. It is widely used in Dutch-style aquariums to provide a strong visual anchor. In nature aquariums, it adds a wild, unruly element to the background or midground.
