Poison Plants

Author is Shay Stratford

A common misconception - toxic plants don't taste good - animals will not eat them!

Healthy Llamas may be more resistent to minor toxic ingestions

Certain conditions will favor the ingestion of poisonous plants - cold weather, drought and herbicides.

Below you will find a list of plant photos to help you with visual identification.. Click on the plant names below to see photos: (photos from Shay Stratford )

REMEMBER:

  • Plants vary with the seasons
  • Plant populations change with time
  • Plant identification can be tricky
  • Look high and low - from ground covers to vines high in trees
  • Remember landscape plants
