Propagating Green Tiger Lotus (Nymphaea zenkeri 'Green')

How to propagate Green Tiger Lotus from daughter bulbs and runners: detaching side tubers, replanting, trimming floating pads, and root feeding for vigorous growth.

Overview

Green Tiger Lotus is the green-leaved form of the tiger lotus, a bulb (tuber) plant in the genus Nymphaea. Water lilies grow from a rhizome that can be tuberous, and the plant carries two leaf forms: somewhat heart-shaped submersed leaves near the bulb, and long-stemmed floating leaves that rest at the surface like lily pads. As a centerpiece plant it draws most of its nutrients through the roots, so it favours a nutrient-rich substrate.

Propagation Method

Green Tiger Lotus is propagated vegetatively, not from topping cuttings. A healthy parent bulb forms small daughter bulbs (side tubers) that can be detached and replanted, and the plant can also send out a runner that produces a baby plant on one side without a bulb. Both routes give you a new, genetically identical plant.

Step-by-Step

Wait until the parent bulb is established and vigorous before harvesting offsets.
Locate a daughter bulb or a runner plantlet that has its own small leaves and roots.
Gently detach the daughter bulb or separate the runner plantlet from the parent.
Plant the offset in nutrient-rich substrate, leaving the top of the bulb exposed so it does not rot.
Trim a few floating pads from both plants to encourage bushier submerged growth.

Conditions for Healthy Growth

Temperature 22-28 C with pH 5.5-7.5 and GH 3-14.
Medium lighting; the plant grows submerged but will throw floating pads under strong light.
Nutrient-rich substrate, as this is a root feeder; CO2 is not required.
Leave the crown of the bulb above the substrate.

Maintenance

To keep a compact, submerged form, clip the lily pad at the base of its stem closest to the bulb. Continuously pruning a few floating leaves keeps the plant from growing too tall and encourages it to grow bushier rather than reaching for the surface. Aim to trim roughly every two weeks.

Common Challenges

If you bury the entire bulb it can rot instead of sprouting, so always leave the top exposed. Floating leaves shading the tank are common with bright light; manage them with regular trimming. A weak parent bulb will not produce daughter bulbs, so let it establish before expecting offsets.
