Rorippa aquatica, scientifically classified as Armoracia (Ammoricia) aquatica, is a fascinating and uncommon rosette-type aquarium plant. Known by several names such as Water Cabbage and Lake Cress, this plant is admired for its finely divided, lace-like green leaves that bring a soft, flowing texture to aquascapes.
Often confused with Armoracia aquatica, this species thrives in nutrient-rich substrates under medium to high light, making it a rewarding addition for aquascapers who want to add variety beyond typical stem plants. Its versatility allows it to shine as both a foreground and midground plant, where it adds natural elegance and depth.

Please keep in mind that Live Arrival Guarantee only guarantees that live stocks will be alive upon arrival. We cannot guarantee that you will continue to have success with them. Many factors, including the aquarium environment, water quality, nutrient, temperature, lighting, filter, and CO2 system, can contribute to the failure to grow live plants and live animals.
Even though our plants are very clean, but we can't guarantee they will be 100% pest-free because we cannot be responsible for your aquarium. Please use it at your own risk. We recommended all customers rinse the plants with clean water and quarantine them before use.
However, plants in tissue culture will be 100% free from pests, algae and never have been contacting with any aquarium.
Please review your state's regulations on restricted plants, as we are committed to not shipping plants that are restricted in your area. Do not release any plants into the wild or waterways, as this can harm local ecosystems by introducing invasive species.
