Title: is the rainbow Eucalyptus poisonous to horses in FL?
Answered by: Jimmy Mills
When we get questions about toxic plants, we consult a series of databases in search of answers (see below)
Toxic Plants Databases
ASPCA dogs & cats
*ASPCA- horses
University of Illinois (common names only)
Plants Poisonous to Horses, An Australian Field Guide
*Poisonous Plants of North Carolina
Cornell University Plants Poisonous to Livestock
University of Pennsylvania Poisonous Plants
Canadian Poisonous Plants Information System
*California Poison Action Line
Four of these (see asterisks *) list Eucalyptus sp. as being toxic to horses. I don’t know why the plant is not listed in the other databases.
While the Rainbow Eucalyptus Eucalyptus deglupta isn’t listed specifically, I would take steps to see that it isn’t available for horses to eat. The younger leaves seem to conain more of the toxic agent.
