Common Name(s):

- Description
-
The mosaic plant is a floating, aquatic, herbaceous perennial in the primrose family, native to Brazil, but often grown as an annual in other climates. While only 4 inches high at maturity, it has colorful floating diamond leaves that form an intricate rose pattern and cup-shaped yellow flowers that blossom in summer. The genus name honors Christian G. Ludwig (1709-1773), a professor at Leipzig. The species name means resembling sedum.
Mosaic Plant requires lots of sun or artificial light, a wet environment, and heavy macro and micro fertilization to produce attractive growth. Flower production requires optimal conditions of light, moisture, and fertilization.To propagate the plant, cut off the floating rosette leaving a piece of the stem. A new rosette will develop on it after a short while.
The Mosaic Plant is not winter hardy in North Carolina and needs to be brought indoors where it can be grown as an annual in containers covered with 6 to 18 inches of 72 degree F. water and rooted in the substrate below the water surface. The water requirements of these plants makes them difficult to overwinter indoors, but they can be placed in large aquariums for that purpose. Use in an aquarium is complicated by light and nutrient requirements.
