Boasting delicate, clover-like foliage that elegantly extends above the water's surface, this vigorous and oxygenating aquatic plant bears a distinctive appearance, characterised by clusters of leaves divided into four leaflets, lending it a unique four-leafed charm. While its green-leaves dominates, occasional hints of reddish or bronze tones emerge, particularly in well-lit settings. Sporting a creeping and spreading growth habit, Marsilea quadrifolia forms a lush, carpet-like mat with runners generating new plantlets. Potentially invasive, it's advisable to keep this plant potted to manage its exuberant spread.


  • Garden care:
    Grow in moist, boggy soils or fully submerged in clear water ponds to a maximum depth of up to 25cm (10") below water level. Check growth to avoid the plant becoming invasive. As with any non-native oxygenator, please do not plant in any place with a connection to a natural body of water. Aquatics can appear a little flaccid after their travel to you but will regenerate once submerged in water.
