ADA Ranunculus inundatus

Ranunculus inundatus is a unique plant that brings a fresh, structured aesthetic to aquascapes. Native to Australia, this species is known for its umbrella-like leaflets and upright, branching growth that forms a low, spreading canopy. Its vibrant green colour and geometric form add a modern, architectural feel to planted tanks, making it a favourite among aquascapers looking for something visually different. Whether used in nature-style layouts or as a clean foreground accent, R. inundatus delivers both texture and contrast.

How to Use Ranunculus inundatus
Ranunculus inundatus is typically planted in the foreground or midground areas of the aquarium. It should be inserted into nutrient-rich substrate in small clumps, with space between plantlets to allow for horizontal spread. This plant grows upward and outward, forming a mat-like network of stems topped with rounded leaves, making it ideal for creating a controlled yet wild appearance. It responds best to moderate to high lighting and thrives with CO₂ supplementation. In ideal conditions, it sends out runners and quickly fills in open space with a bushy, dynamic growth habit.

Maintenance
Ranunculus inundatus requires moderate maintenance, especially in high-tech aquariums. It benefits from regular trimming to control vertical growth and encourage lateral spread, as it can become leggy under lower light. Proper spacing at planting time will help prevent overcrowding as it expands. A nutrient-rich substrate and consistent dosing of macro- and micronutrients, especially iron, will support healthy leaf development and coloration. CO₂ injection is strongly recommended to promote compact, lush growth and prevent legginess. It thrives in water temperatures between 20–28°C, making it well-suited for tropical setups.

Emersed Growth
This plant adapts well to emersed conditions in high-humidity environments such as paludariums or Wabi-Kusa. When grown emersed, Ranunculus inundatus retains its charming leaf shape and produces a slightly more robust form. In some cases, it may flower with small, delicate yellow blooms. Keep the substrate consistently moist and provide bright, indirect light for best results in emersed settings.
