Solved Seedling identification

Can anyone identify this? Found it outside my classroom growing between some stones.

 

I think it might be a sycamore seedling.
I found a variegated one many years ago and its quite a large tree now.

 

Thank you, @pete. Did it keep its variegation?

 

Yes, and mine has orange new growth early in the season.
I'll see if I can get a picture.

Tomorrow its nearly dark now, and the camera keeps icing up

 

Thank you. I shall look after it and see how it grows.

 

They get big so I have to cut mine back, but a couple of pictures.


New growth.

 

It’s lovely, I like the red petiole as well.
