Fun Facts

  • 🌱 Parsonii is named after its appearance and the Parson's orchid, reflecting its aristocratic, refined look with bold striping patterns.
  • 🌱 Calathea plants are called 'prayer plants' because their leaves fold up at night in a process called nyctinasty, moving upright like hands in prayer.
  • 🌱 The pink stripes on Parsonii's leaves are caused by selective pigmentation; the pattern intensity can vary based on light exposure and plant health.
