Ranunculus inundatus (River Buttercup) care guide
Ranunculus inundatus · Ranunculaceae
Ranunculus inundatus (River Buttercup) (Ranunculus inundatus) is an aquatic plant. It belongs to the Ranunculaceae family. It is native to Eastern and southeastern Australia – wet mud and shallows at the edges of ponds, swamps and rivers; grows submerged or emersed. It needs high light. Water temperature: 20°C – 28°C. pH: 5.0 – 7.5. Care difficulty: Moderate. Growth rate: moderate (slow start, then spreads).
How do you care for Ranunculus inundatus (River Buttercup)?
| Light | High (medium at minimum; weak light gives tall, leggy leaf stalks) |
|---|---|
| CO₂ | Recommended (sources range from medium demand to 20 – 40 mg/l) |
| Temperature | 20°C – 28°C |
| pH | 5.0 – 7.5 |
| Placement | Foreground to midground (foreground under strong light) |
| Growth | Moderate (slow start, then spreads) |
| Difficulty | Moderate |
| Family | Ranunculaceae |
How do you trim and propagate Ranunculus inundatus (River Buttercup)?
Regularly thin out runners and old, tall leaves to keep the group airy and low. Propagate from the daughter plants on runners from the creeping rhizome: cut them off and replant a few cm apart.
What problems affect Ranunculus inundatus (River Buttercup)?
The plant sits still for weeks after planting — a normal adaptation period of roughly two weeks to a month; stretched leaf stalks from too little light.
How do you fix Ranunculus inundatus (River Buttercup) problems?
Keep conditions stable and wait; increase light or move it somewhere brighter. Use fine aquasoil, CO₂ and regular macro and micro fertiliser. It tolerates cooler water than most tropical carpet plants; the yellow buttercup flowers appear only in emersed culture.
Where does Ranunculus inundatus (River Buttercup) come from?
Eastern and southeastern Australia – wet mud and shallows at the edges of ponds, swamps and rivers; grows submerged or emersed
