  • Features: Striking spathe and spadix, along with glossy, arrow-shaped leaves, set it apart from more common aroids

Taxonomy & Classification

  • Genus: Ayuantha
  • Botanical Background: Described by A. Hay and later revised by S.Y. Wong and P.C. Boyce, the species reflects modern botanical research methods and reclassifications within the Araceae family.

Natural Habitat & Distribution

  • Uniform green coloration

Inflorescence (Spadix & Spathe)

  • Prominent spathe that may display vibrant hues, paired with a compact spadix
  • Not heavily scented, this structure is well adapted to its natural pollinators

Growth Habit

  • Terrestrial herbaceous perennial that grows from a rhizome, establishing a compact clump that is ideal for container cultivation
