Cardamine lyrata
Cardamine lyrata is actually a marsh plant from Japan. But it is also a familiar aquarium plant which thrives under water with 20-50 cm long stems. A characteristic trailing growth form makes it highly decorative, and ‘aerial’ roots often form on the plant itself.

Grew well in my aquarium with low light. The trailing stems add a nice natural look. I kept the water temperature under 28°C and noticed the leaves stayed small and the plant became more defined.

Planted in a group and it spread nicely. The aerial roots are a unique feature. Works well in a semi-transparent tank with medium CO2.

Perfect for a summer pond. Grows quickly and looks lush. I didn’t need to adjust lighting much, and it adapted well to the environment.
