Originally Polka Dots were known for the bright pink spots which covered their dark green foliage. Now you can also find hybrids with bright red or white spotting. The Polka Dot plant needs bright light but not full sun. It does best in a humid environment, so occasional misting is helpful. The soil should be kept slightly moist. It is best to water this plant with rainwater or tap water which has been allowed to set for 24 hours so that chlorine and other chemicals can dissipate from it. Polka dots can tend to get leggy with age, so keep it pinched back to no taller than about 16 inches. This plant isn't harmed at all if you feel the need to cut it back hard. You can easily root these cuttings to create new plants.
