Ranunculus inundatus

Ranunculus inundatus - A Unique, Umbrella-Like Foreground Aquarium Plant for Aquascapes

Ranunculus inundatus is a distinctive foreground-to-midground aquarium plant known for its umbrella-shaped leaves that grow on upright stems from horizontal runners. This species creates a textured, architectural look ideal for Iwagumi or Nature-style aquascapes, where structure and contrast are key.

Native to Australia, this creeping plant grows best under medium to high light with CO₂ injection, which encourages tight growth and bold leaf formation. In low-tech setups, it may grow taller and lose some of its compact appeal.

Ranunculus inundatus sends out horizontal runners that spread across the substrate, producing new vertical shoots. When properly maintained, it forms a layered, grassy network that provides visual interest and habitat for shrimp and small fish.

Plant in nutrient-rich soil and trim both runners and vertical growth as needed to maintain shape. A favourite of advanced hobbyists looking to elevate their scape with something less common.
