Ranaculus Innunduatus also called ‘river buttercup’, is an amphibious plant native to South-Eastern Australia.
It can be seen growing on moist mud or in ponds and rivers.
Many Ranunculus (buttercup) species can be found in wetlands around the world, but R. inundatus is one of the few that can also grow submerged.
Ranunculus inundatus is a low-growing plant that provides dense coverage at the bottom of your tank and has umbrella parsley-like leaves.
It can grow quickly and send stolons through the substrate’s surface.
These runners will grow new leaves and can be separated from the mother plant to form new plantlets that are self-sufficient.
Ranunculus innundatus, as a fast-growing plant, requires consistent micro-macronutrient supplementation with conventional aquarium fertilizers (and fish poop).
This amazing Australian plant can adapt to a wide range of water hardness and pH values, making it suitable for all types of tap water. It’s a one-of-a-kind accent and a great addition to a well-curated aquascape, and it can even be the major focal point.
R. inundatus can be utilized as a midground or foreground plant in an aquascape, and it makes a wonderful accent or focal-point arrangement. This plant should be used in the midground if lower lighting levels are used, so the higher stems can be disguised by hardscape or foreground plants. High illumination levels in the foreground promote shorter leaf height, which helps to retain the impression of scale in a layout.
- Needs lots of light. Under low light, it forms long leaf stalks, which gives it a much less attractive overall look.
- Plants require strong light, the river buttercup needs around 30 mg/l of CO₂ and ample fertilization.
