Title: Is non-native Ixora poisonous to horses?
Answered by: Nan Hampton


My horse was eating an ixora bush at a park in south florida. Is the Ixora shrub poisonous to horses?


No species of Ixora is listed on the Toxic and Non-Toxic Plant List – Horses from the ASPCA.  The ASPCA also lists both Ixora javanica and Ixora coccinea as "non-toxic" to cats or dogs.  It probably doesn't occur on the ASPCA list for horses as "non-toxic" because it generally is a non-native ornamental that wouldn't be encountered by horses.  I think your horse will be fine.  Maybe the Ixora plant didn't fare so well, though.
