This is what creeping indigo poisoning looks like. It kills all animals and wildlife, not just horses. I've tried to tell friends and family and I have been treated as over reactive. Unfortunately I have seen it at many of your places, at shopping centers, parks ect. It spreads easily by vehicles and you will find it near driveways first but beware, it is fast spreading and hard to kill. It grows all year long and has no dormant period. It also hides underneath the beautiful green grass unbeknownst even on well maintained properties. This is a serious concern to all of Florida agriculture, wildlife and UF scientists. Please familiarize yourself with this deadly non-native plant. I will post pictures of creeping indigo.
