Musk Thistle

 

Musk Thistle closeup.

 

Musk Thistle plant.

   

  • 10,000 seeds can be produced annually and may remain viable for 15 years.
  • Prickly leaves ending in sharp spines make this plant very undesirable to grazing animals - even goats ignore this plant!
  • Because this plant can self-pollinate, even one plant can easily expand into a large infestation.
