Here is a nice list of wild plants, herbs and some cultivated crops that are toxic to sheep and, lower down, there is a list of plants that they loooove. We have some of both around our field. Lupins are in bloom at the moment so we need to make sure they don't spread into the sheep's field and I think I will move the philodendron that I planted near the sauna a couple of years ago. It's surrounded by chicken wire to keep the sheep off but I might just as well put it up near the cabin where we enjoy the smell. Buckthorn are also toxic to sheep but we have a fence around ours and they seem to be dying anyway - not sure why but it could be due to the weed situation which is difficult to manage when there is chicken wire everywhere!
