Marsilea quadrifolia, Four Leaf Clover or European Water Clover, makes an excellent foreground plant for tanks with low light. In its natural habitat, Europe and Southern Asia, it is found growing both submersed and immersed along marshlands, riverbanks and streams. Considered an invasive exotic in North America. Adaptable to low and bright light conditions; CO2 and nutrients encourage faster than normal growth. When submerged in the aquarium it's terrestrial stem-like form transforms into a lower substrate creeping/carpeting plant that slowly spreads through runners across the substrate. Shorter, more compact growth achieved in brighter light.

Plants that have been grown immersed will require extended adaptation period for submersed growth in the aquarium. You may consider cutting plants and removing immersed grown leaves to allow new leaf growth in aquarium; new growth will happen after a short time.
