I have a bunch of Psychotria carthagenensis/ alba plants I'd like to put along a fenceline in NSW There's a small chance that cows could get to them when they're taller ( the plants, not the cows ) Google has some loose insinuations that some Psychotria species could be potentially toxic to cattle, however most of the search results don't mention species and Psychotria is a large and varied genus B&T World Seed has a reference saying P. viridis is toxic to cattle, but I can't find the study reference for that. And I'm planting P. carth Has anyone here had P. carth within range of cattle reach? What were your experiences- cows OK? If cattle are known to be affected by it I'll plant them somewhere else
