Nymphaea Micrantha care guide
Nymphaea Micrantha (Nymphaea micrantha) — medium light, 22-28 °C, pH 5.5-7.5, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Nymphaea Micrantha (Nymphaea micrantha) is an aquatic plant of the family Nymphaeaceae, listed in the Aquairi knowledge base as an intermediate-level species. It is typically grown under medium light and without obligatory CO2 injection on nutrient-rich aquasoil. A smaller relative of the popular Tiger Lotus. Produces attractive green leaves with dark spots and occasional red tints. Grows from a bulb and can be kept compact by trimming floating leaves. An eye-catching midground specimen that adds a wild, natural look to aquascapes.
Taxonomy
- Family: Nymphaeaceae
- Genus: Nymphaea
- Scientific name: Nymphaea micrantha
- Common synonyms: Small-flowered Water Lily, African Tiger Lotus
Habitat
Nymphaea is a cosmopolitan genus of water lilies (Nymphaeaceae) inhabiting still and slow-moving fresh waters worldwide. Plants grow from a tuber producing submersed and floating leaves. In the Aquairi knowledge base, populations associated with this form are recorded from West Africa.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7.5
- GH: 2-12 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 25 cm
- Growth rate: medium
- Recommended placement: midground
Placement
Midground or background tuber plant; submersed leaves form a striking rosette, but if floating leaves are allowed to develop they shade the layout. In the Aquairi knowledge base this form is recommended for the midground under medium light and without obligatory CO2 injection, using nutrient-rich aquasoil.
Propagation
Reproduces vegetatively by side tubers and rhizome fragments; large tubers can be cut to encourage daughter shoots. Documented propagation techniques for this entry include: adventitious plantlets.
Common issues
Allowing floating leaves to mature triggers blooming and depletes the tuber; cutting floating leaves at the petiole keeps the plant submersed.
Propagating Nymphaea micrantha by Adventitious Plantlets
Overview
Nymphaea micrantha is a small viviparous water lily in the family Nymphaeaceae, a compact relative of the popular tiger lotus. Water lilies are rhizomatous or tuberous perennial herbs that grow mostly floating leaves on petioles, and they reproduce vegetatively through proliferating structures in addition to seed. In Nymphaea micrantha that vegetative habit is striking: the plant grows from a bulb-like rhizome and is a medium-growth, root-feeding species suited to the aquarium midground under medium light.
Propagation Method (Adventitious Plantlets)
This species is propagated mainly by the adventitious daughter plantlets it produces directly on the leaf, at the point where the blade meets the petiole. Each plantlet develops its own miniature leaves and roots while still attached to the parent, so propagation is simply a matter of letting these vegetative offspring mature and then separating them. The bulb-like rhizome can also be divided as a secondary method.
Step-by-Step
- Inspect mature leaves and identify daughter plantlets forming where the blade joins the petiole.
- Wait until each plantlet has its own small leaves and a developing root cluster.
- Detach the rooted plantlet from the parent leaf with clean fingers or scissors.
- Plant the plantlet in nutrient-rich substrate, burying the roots but keeping the crown exposed.
- To divide the rhizome instead, lift the bulb and cut it so each piece keeps roots and at least one growth point, then replant.
- Allow new floating pads to surface, trimming them periodically to keep the plant compact.
Conditions for Healthy Growth
Provide medium light and a temperature of 22-28 C, with pH 5.5-7.5 and GH 2-12. As a root-feeding bulb plant it benefits from a nutrient-rich substrate; CO2 is not required. The species can also grow emersed.
- Lighting: medium
- Temperature: 22-28 C
- pH: 5.5-7.5, GH: 2-12
- Substrate: nutrient-rich (root feeder)
- CO2: not required
Maintenance
Because water lilies push leaves toward the surface, trim floating pads roughly every two weeks to keep the plant in the midground and let light reach lower plants. Remove old or damaged leaves at the base, and keep root tabs replenished to sustain the bulb's vegetative output.
Common Challenges
- Plantlets detached before rooting are slow to establish or melt away.
- Unchecked floating pads shade out neighbouring plants and dominate the surface.
- A bulb left undisturbed in poor substrate slows down and produces fewer plantlets.
