Who is the Whorled pennywort?
This variety of Hydrocotyle is an exception among its genus since it remains mainly a creeping plant, which makes it a first choice plant to dress the foreground of the aquarium. It will form a network of stems sprinkled with small parasols. However, you can also use it as a floating plant, which will bring it closer to the light source, which it loves.
This species of plant can also live out of the water as long as there is a constant supply of wetland. It is therefore perfectly possible to use it in an aquaterrarium or wet terrarium. Under these conditions, you can hope to see it bloom in the summer.

To grow well, this plant absolutely needs intense light. Moreover, it will only remain crawling under this condition since it stops growing tall once it has found enough light.
If you wish to use it in crawling mode, it will have to be installed in light soil and aerated to allow the roots to spread without difficulty.
As far as water parameters are concerned, opt for soft, slightly acidic water, with an ideal temperature of between 22 and 25°C (72 to 77°F).
Even under good maintenance conditions, it grows relatively slowly with the production of about one leaf per week.
CO2 is not essential for this species.
