Can anybody identify this plant?

Hi
I have a lot of this growing around my driveway and garden.
Not sure if I'm in the right place to post this as technically it's a weed not a plant.

 

I think it might be ragwort.

 

Ah ok,but I thought ragwart has yellow flowers,we have to pull ragwart up out of our horses field because its poisonous to horses.

 

Give it time, give it time.

 

Yeah I think your right,there seems to be 2 varieties the tall flowering type and this one.

 

I think you will find this turns into the tall flowering kind.

 

Ah ok,yeah my daughter just told me that lol,she said it won't flower because it's in the shade most of the time.

 

I think it will flower if you leave it long enough, lots of plants go through this stage of forming a low rosette of leaves before going on to form a long flowering stem.

 

Well that's coming up tomorrow then lol

 

Dispose of it carefully as I read it is more dangerous when dead.

 

Yes, apparently as it dries it gets sweeter to eat, so when digging it out of pastures you have to get rid of it well away from the horses.

 

I was under the impression regarding horse feed that when dried and used as winter feed the horses just eat it.
But for a few years now I've driven by a field with horses in it and they just dont touch the stuff, the field they are in is full of it but they never eat it.

 

No, hay sellers try to tell you that they ensure their fields don't have ragwort. It is really nasty - horses sometimes eat it if nothing else available, and it causes slow horrible liver damage

I think it grows as a flat rosset one year and then grows tall and flowers in the next year. It may also regrow from small pieces of root so be as thorough as possible good luck
