Poisonous Plant Quiz
Sorry! That's the wrong answer. This weed is St. John's-Wort,
which occurs throughout Ontario in pastures, edges of woodlots,
roadsides, abandoned fields, water areas and occasionally in lawns
and lower borders.
Treatment: Avoid pasturing horses where this weed is abundant or keep animals under shade during normal sunny days.
A veterinarian should be consulted immediately for supportive treatment to reduce the damage caused by ingestion of poisonous plants.
