Established Mature Plant

6+ months ongoing

Full-sized plant (12-24 inches tall) with numerous variegated leaves; plant is robust and fills its container

Fun Facts

  • 🌱 Pinstripe Plants are also called 'Peacock Plants' and belong to the prayer plant family (Marantaceae), named for their leaf-folding behavior that resembles hands folded in prayer at night
  • 🌱 The plant is native to the Colombian tropical rainforests and thrives in humid understory conditions, which is why it demands consistent moisture and humidity in cultivation
  • 🌱 The pink or white stripes follow the leaf venation patterns, and the intensity of the coloration increases with proper light, humidity, and nutrition—stressed plants may fade to solid green
