Aponogeton undulatus Care Guide
Aponogeton undulatus is a South Asian species of the family Aponogetonaceae with pale-green wavy-edged leaves that reproduces readily via plantlets.
Overview
Aponogeton undulatus is a submerged aquatic plant in the family Aponogetonaceae. It produces very pale-green leaves with undulating (wavy) margins, growing from an ovoid rhizome. The true species does not produce floating leaves, although some hybrids do. It tolerates a wide range of water conditions and is used as a background or midground plant.
Taxonomy
- Family: Aponogetonaceae
- Genus: Aponogeton
- Scientific name: Aponogeton undulatus
- Common name: Wavy-edged Aponogeton
Origin
The species is native to India, Bangladesh, Myanmar and Sri Lanka, where it occurs in lakes and ponds across South and Southeast Asia.
Habitat
It grows submerged in still or slow-moving fresh waters and tolerates most water conditions, preferring bright positions but able to grow in partial shade. Some populations enter dormancy in winter and can be held at lower temperatures, while others grow year-round.
Tank requirements
- Temperature: 22-28 °C (tolerant 17-30 °C)
- pH: 6.0-7.5
- GH: 3-14 °dGH
- Lighting: medium to high
- CO2: not required; tolerates 10-40 mg/L
- Substrate: nutrient-rich
- Maximum height: about 40-50 cm
- Placement: background / midground
Planting & care
The rhizome is planted in nutrient-rich substrate. The plant is undemanding and tolerates most water conditions, with medium-paced growth in bright light. It is among the easier Aponogeton species to keep.
Propagation
Propagation occurs through adventitious plantlets that form on the flower stalk (proliferating inflorescences), as well as by seed; flowers can be hand-pollinated with a fine brush and seeds germinated in sand or fine gravel under shallow water.
Difficulty
The species is rated beginner-friendly. Its tolerance of varied water parameters and easy vegetative propagation make it suitable for less experienced aquarists.
