Summary

  • Worldwide distribution. In Australia and most Pacific island countries. A vine and epiphyte in tropical and subtropical countries. An environmental weed, smothering native forests, but also along roadsides. Tolerant of shade, drought, high rainfall, different soil types. Poisonous.
  • Stems, green, flexible to 8 m, clinging to host with dense, short, aerial roots. Leaves, alternate, green or variegated, very large, oval, broad at base, pointed tips, becoming divided when old. Flowers, like taro, with sheaf around central spike; rarely produced.
  • Spread: cuttings, stem fragments, seed (where produced) by birds. Longer distances in domestic and international trade for ornamental and medicinal plants.
  • Biosecurity: high risk. In Florida Category II weed, invasive, but not yet disruptive of plant communities. Readily available on Internet.
  • Biocontrol: Investigation of potential suggested.
  • Cultural control: hand-pulling; collect stem pieces and burn. Probably, repeated applications necessary.
  • Chemical control: triclopyr or glyphosate. Leaf spray or cut stump/paint treatments (see Fact Sheet no. 546). Test herbicide as it may pass into host via roots of taro vine.

Common Name

Taro vine. It is also known as centipede tongavine, devil's ivy, golden pothos, monstera, dragon-tail plant, and money plant.

Scientific Name

Epipremnum pinnatum. Previously, it was known as Epipremnum aureum, Epipremnum pinnatum cv. Aureum, Monstera pinnnatum, Pothos pinnatus. It has a confused taxonomy. Note, Epipremnum aureum is treated as a synonym of Epipremnum pinnatum by some taxonomists, although others believe it to be more robust. Epipremnum species are members of the Araceae.
