It's a large white fig. I hope you guys can help me identify (if it fruits :-)

Is one end buried in the soil? I lay my cuttings in a shallow trench but I cover the entire thing so it has a lot of chances to root.

Yes, the end with the roots :-)

I stored the tree in a cold shed. Now I plan to leave it in the ground permanently. I laid the tree sideways to keep height down so I can protect during winter.

I see! That's a good idea for your zone.
