Title: Are non-natives, Dappled willow and Kousa dogwood, toxic to horses?
Answered by: Nan Hampton

QUESTION:

Are dappled willow trees/bushes or kousa dogwood trees toxic to horses?

ANSWER:

First of all, our focus and expertise here at the Lady Bird Johnson Wildflower Center are with plants native to North America.  Neither Salix integra 'Hakuro-Nishiki' (Dappled willow) nor  Cornus kousa (Kousa dogwood) are North American natives; both are Asian natives.  Nevertheless, Mr. Smarty Plants can guide you to several toxic plant databases—some specific for horses and some general—that you can use to find out if your plants are toxic to horses. A quick search in the four last databases on the list below (the general ones) did not show either of the species above, nor were there any entries at all under the two genera (Salix or Cornus).  You should search through the horse toxic plant databases for both plants and keep these databases in mind when you have questions about other plants.
