Wow, thank you all for those very quick replies! It's probably something we'll want to get rid of then, but at least it's not too worrying. From doing some research now I know what it is, it looks like you don't want to let horses eat too much of it, but a little bit is ok.
Thanks again everyone!
Hi all,
I'm new to the forums, so firstly "hello"!
I'm trying to identify this plant that seems to be growing in patches all over the fields at our place. Does anyone have any idea what it is and whether it's going to be a problem when we come to put the horses out there? Is it poisonous...
