Plant Profile
Ranunculus Inundatus, known as River Buttercup, is a creeping aquatic plant that looks like nothing else in the hobby. It has deeply palm-lobed, starburst leaves that sprout from horizontal runners like a forest of tiny green umbrellas, spreading across the substrate via underground runners. It works as an eye-catching foreground carpet or low midground accent, and it's just as happy in submerged setups as it is in emersed Wabi Kusa or dry-start builds, bringing architectural texture that high-tech layouts don't usually get elsewhere.
Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Benefits
- Unique starburst and umbrella-like leaf shapes introduce bold architectural contrast into foreground and midground zones.
- Rapidly spreads across the substrate to form a dense foreground carpet.
Care & Planting Instructions
-
Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions.
- Use fine-tip pinsettes to plant small stem clusters 1 inch apart into aquarium soil.
- Provide high-intensity lighting and pressurized CO2 injection to encourage low, creeping horizontal growth; tall vertical stretching indicates insufficient light, while pale or thin foliage signals a CO2 or micronutrient deficiency.
- Maintain stable water parameters and avoid sudden parameter swings to prevent leaf melting or root decay.
- Trim horizontal stolons or upright stems with curved scissors, and replant individual cuttings directly into substrate to propagate and expand coverage. Read our trimming & propagation guide for details.

Frequently Asked Questions
1. Why is my Ranunculus Inundatus growing tall and leggier instead of staying low?
Ranunculus Inundatus stretches vertically when it receives insufficient lighting. To keep stems short and induce low, horizontal creeping runners across the substrate, increase light intensity and maintain adequate pressurized CO2 levels.
2. Why are the leaves of my River Buttercup turning yellow or thin?
Yellowing leaves usually point to a macro or micronutrient deficiency (such as iron or nitrogen), while abnormally thin or fragile foliage typically hints at insufficient CO2 levels in the water column.
3. How do I prepare Ranunculus Inundatus Tissue Culture before planting?
Carefully remove the gel from the roots by washing the plant in a bowl of room-temperature water or gently rinsing it under a tap. Once the gel is removed, separate the dense runner cluster into smaller individual plantlets and plant them into substrate using fine pinsettes.
