Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: is the rainbow Eucalyptus poisonous to horses in FL?
Answered by: Jimmy Mills

QUESTION:

Is the Rainbow Eucalyptus Tree poisonous to horses?

ANSWER:

When we get questions about toxic plants, we consult a series of databases in search of answers (see below)

Toxic Plants Databases

 * The Merck Veterinary Manual 

ASPCA   dogs & cats  

*ASPCA- horses

Wikipedia

University of Arkansas 

University of Illinois  (common names only)   

Plants Poisonous to Horses, An Australian Field Guide                                            

Toxic Plants of Texas

*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

Manes and Tales Organization

IFAS Extension

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.
