Pearl weed is a bright green, low-growing stem plant perfect for beginners. It is a versatile species which can be used for both foreground, midground and background. Constant pruning will keep it low growing and spread runners horizontally. Leaving it untrimmed will allow it to grow vertically as a background plant. The shape and growth of the plant depends on the conditions so you must plan accordingly if you have a specific vision for how it will fit into your aquascape. This plant is similar in appearance to other carpeting plants, and can be a low-maintenance alternative if you are having trouble getting foreground coverage in your tank.
