The pink splash plant, also called the polka dot plant, is a low-growing bush that grows to a height of 12 inches. Although it is popular as a houseplant, the pink splash can be grown outdoors and the pink, white and rose freckles of the foliage provide an attractive companion to flowering plants, such as impatiens. Native to Madagascar, the pink splash thrives in a porous soil mix, with lots of organic matter. The pink splash plant is hardy to USDA Zones 10a and 11.
Provide bright but filtered sunlight for your pink splash plant. It will tolerate a bit of sun, and some shade, but the color of the leaves is best when the plant gets bright, indirect light.
Water the plant frequently, as often as two times a week. Poke your finger into the soil and if it feels dry just below the surface, the plant needs to be watered. If the plant begins to wilt that is another sign that it needs water.
Feed your pink splash plant monthly with balanced fertilizer, such as 20-20-20, according to the package directions.
Mist the plant with a fine mist of water a few times a week. During the winter the plant may require more frequent misting, depending upon how dry the air in your home is.
Pinch the tips of the plant to encourage it to get bushier and don't be afraid to cut it back if it gets too leggy. You can root the cuttings in a pot of lightweight potting soil or sand.
Inspect the pink splash plant occasionally for powdery mildew, whiteflies, and mealy bugs. The least toxic remedy for these pests is insecticidal soap.
