can anyone tell me what this plant is called? it just appeared in my garden

I have know idea Bayleaf but its very interesting.I hope someone can I-d it as I would like to know.

Hi Bay... will try and find the name..
I have it too. It sends out runners and in no time it will take over! so be careful to keep it in check.
The flowers are sweet nd bright like orange little suns. but like a Dandylion it will spread!!

Could be a Straw Flower ? I need to see a Close up Of Its Flower Bud 2 ID better Sorry :/

Looks like Hieracium aurantiacum - Hawkweed, Fox and Cubs. Very invasive, spreads by runners and seeds like dandelions.

RRrrrrrr a Wild Flower then :)

Also known as Grim the Collier for some reason.

Look up Pilosella Aurantiaca I think you will find it to be, if so I have it and the leaves are like a roset and hairy at the bottom of the plant with a long hairy stalk with the orange flowers in a little clump at the top, as they say it seads like a dandilion. I presume you have taken the photograph from directly over it which does not show it as a long stem protruding from the centre of the roset of leaves.

Pilosella Aurantiaca and Hieracium aurantiacum are the same plant, just Botanists changing things around.

Yes, I think Hieracium. I took some seed from one once but then decided it was a bit wild-looking. I still get bits coming up now and then. Spreads around madly if you let it, but would be good in a wild garden.

Thank you all i can confirm that it is hawkweed . I do like it an so I am going to move it to a wild part of my garden.

But will it stay there, Bayleaf?

Saw it in a 'meadow' like setting with tall buttercups the other day. It looked great.
