Did you know

  • Geranium maderense is the largest species in the entire Geranium genus, producing a spectacular dome of flowers up to 5 feet across.
  • A single plant can produce over 1,000 flowers in a massive inflorescence before dying after blooming, a strategy called monocarpy.
  • The dead leaf stalks bend downward to form prop-like supports that hold the heavy flowering stem upright, a remarkable structural adaptation.
  • It is endemic to Madeira Island, where it is now rare in the wild due to habitat loss but thrives in cultivation worldwide.
  • The species was first described scientifically in 1787 from plants growing in the laurel forests of Madeira at around 3,000 feet elevation.
