Overview
Nymphaea lotus is an aquatic plant in the family Nymphaeaceae. A striking bulb plant with broad arrow-shaped leaves covered in reddish-brown speckled patterns. If allowed, it sends lily pads to the surface, but regular trimming of surface runners keeps its dramatic underwater foliage compact and colorful.
Taxonomy
- Family: Nymphaeaceae
- Genus: Nymphaea
- Scientific name: Nymphaea lotus
- Other names: Tiger Lotus, Nymphaea Lotus
Habitat
A water lily native to East Africa, the Nile basin and Southeast Asia, found in ponds, oxbow lakes and slow-flowing waters. Grows from a tuberous rhizome and naturally sends floating round leaves to the surface; aquarium cultivation typically trims surface runners to keep the submerged colour foliage compact.
Growth requirements
- Light: medium (≈50-80 PAR at substrate)
- CO2: optional (CO2 improves growth and coloration)
- Temperature: 22-28 °C
- pH: 5.5-7.5
- GH: 3-12 °dGH
- Substrate: nutrient-rich aquasoil or fertilised gravel
- Nutrient demand: medium
- Growth rate: fast
- Difficulty: intermediate
Placement
- Recommended placement: midground
- Maximum height: 50 cm
- Trim every: 7 days
Propagation
In cultivation the plant is propagated by vegetative division or fragmentation and runners (daughter plants on horizontal stolons).
Propagating Nymphaea lotus (Red Tiger Lotus)
Overview
Nymphaea lotus, the tiger lotus, is a bulb plant found in East Africa and Southeast Asia. It grows from stoloniferous, branched rhizomes (the aquarium 'bulb') that persist through dry seasons and bear leaf scars. In the aquarium it produces leaves under the water surface as well as lily pads that reach the surface, and it can grow relatively quickly once established, even under low light.
Propagation Method
Tiger lotus is propagated from its bulb, not from cuttings. The stoloniferous rhizome sends out runners and forms daughter bulbs and side offsets, which can be separated once they have their own leaves and roots and replanted as new plants. This is division of the bulb's offsets rather than topping a stem.
Step-by-Step
- Locate a daughter bulb or side offset growing on a runner from the parent rhizome.
- Once it carries its own leaves and roots, gently separate it from the parent.
- Plant the offset in rich substrate, leaving the top of the bulb exposed so it does not rot.
- Add root tabs near the bulb, since the lotus is a root feeder and grows faster with substrate nutrients.
- Expect new leaves to appear within about 7–14 days once the offset is established.
Conditions for Healthy Growth
The tiger lotus is undemanding about light and can thrive even under low light, growing relatively quickly once established. It is a root feeder, so rich substrate and root tabs support strong growth. Its leaves are delicate and are easily damaged, so handle young offsets carefully.
Maintenance
Left alone, the plant sends lily pads to the surface. Regularly trim the surface runners and pads to keep the dramatic underwater foliage compact and colourful, cutting the runner before it reaches the surface. Trimming surface growth redirects energy into the submerged leaves and into producing more offsets.
Common Challenges
- Surface lily pads shading the tank when runners are not trimmed back.
- A buried or rotting bulb if the top is planted too deep instead of left exposed.
- Delicate leaves tearing easily, so newly planted offsets need careful handling.
