Accession Data:

Gunnera tinctoria (Molina) Mirb.

  • Common Name: Chilean Prickly Rhubarb
  • Family: Gunneraceae Meissner.
  • Synonym(s): Panke tinctoria Molina

  • Country of Origin: C. & S. Chile to SW. Argentina
  • Habitat: streams and damp locations

  • Description: Bergman and Osborne (2002) report that at the end of the nineteenth century it was found that Gunnera tinctoria forms a symbioses with nitrogen fixing Cyanobacteria inside its cells. The Cyanobacteria have been classified as belonging to the genus Nostoc. There is little evidence that the host (including G. tinctoria) can survive to maturity in the absence of the cyanobacterium, and all cultivated and naturally growing plants contain the cyanobiont, irrespective of nutrient availability.5
  • Culture: Has invasive potential in some locales (Great Britain, Ireland, New Zealand). Cultivate in container culture only.
