I’ve noticed this on one of my stunted nigra seedlings. All the rest (stunted and normal) have regular heart-shaped leaves like the parent tree in my posts above.
The next nigra (presumably it’s clone) is ~120m away. I have albas growing ~30 and 100m from it and my neighbour has a Pendula (likely non- hybrid alba) ~35m away. Nothing else within 250m.
I don’t know of any fig-leaved nigra in the area. All old trees I’ve found around have heart-shaped leaves.
Ideas?
