The mosaic plant (Ludwigia sedioides) forms stunning floating rosettes of small diamond-shaped leaves that look like a mosaic tile pattern on the water. Rooted in soil with long stems reaching the surface, it is a favourite for garden ponds, lotus bowls and balcony water tubs across India.
Quick answer: Ludwigia sedioides is a tropical surface plant for ponds and tubs, not small aquariums. Plant it in a pot of heavy soil 20–60 cm under the water, give it at least 4–6 hours of sun, keep water warm above about 20 °C, and feed with aquatic fertiliser tabs. It grows fastest in Indian summers and slows or dies back in cold North Indian winters.

How to plant a mosaic plant in a tub or pond
- Fill a small pot with heavy garden soil or clay; avoid light potting mix that floats.
- Plant the roots and cover the soil with a layer of gravel.
- Lower the pot gradually so leaves can reach the surface; start shallow and go deeper as stems lengthen.
- Place the tub where it gets morning and some afternoon sun.
- Push an aquatic fertiliser tab into the soil every 4–6 weeks during the growing season.
Why grow it in India?
Indian weather suits Ludwigia sedioides for most of the year. Warm temperatures and strong sunlight make it spread quickly from March to October. Its leaves turn red-tinged in full sun, it shades the water to reduce algae and keeps tubs cooler for fish such as guppies and mollies, and its rosettes pair beautifully with water lilies such as the Red Tiger Lotus.
Seasonal care
- Summer: fastest growth; top up evaporated water and thin rosettes that overlap.
- Monsoon: prevent tubs overflowing and washing plants out; drill an overflow hole if needed.
- Winter (North India): growth stops below about 15–18 °C; move small tubs to a sunny, sheltered spot or indoors under light.
Common problems
- Leaves yellowing: nutrient shortage; add fertiliser tabs.
- Rosettes shrinking: too little sun or water too cold.
- Holes in leaves: snails or insects; remove pests by hand.
- Mosquito larvae in tubs: add small fish like guppies.

Frequently asked questions
Can I grow mosaic plant in an aquarium?
Only in large, open-top, very bright tanks. It needs lots of light and surface space, so ponds and tubs are much better.
Does Ludwigia sedioides need soil?
Yes. It is rooted in soil with stems growing up to the surface, so plant it in a pot rather than floating it loose.
How fast does the mosaic plant spread?
In warm, sunny weather a single plant can produce several new rosettes within a few weeks.
