Title: Toxicity of Fan Tex Ash tree to horses
Answered by: Jimmy Mills
When Mr. Smarty Plants gets questions about toxic plants, he heads to the Toxic Plant Databases listed below. I could find no listing for the Fan Tex Ash. Not finding a listing doesn't gaurantee that it is non toxic, but it lessens the probability.

For a little background on the tree, this is an excerpt from a previous answer.
Fantex is a cultivar of Fraxinus velutina (Arizona ash). Rather, Fantex is a "sport", or mutant form, of ash that was selected and developed by Fanick's Nursery in San Antonio for its different leaf type—its leaves are smooth; whereas the regular F. velutina leaves are somewhat fuzzy on the underside. There is, however, great variety in the texture of the leaves of this species. Additionally, Fantex apparently has a thicker leaf and is sterile (producing no seeds). It is always grafted onto Fraxinus velutina root stock according to the Pima Arizona Cooperative Extension.
