this is a colorful leaf that's on the pear tree that the town planted in front of our house a couple of years ago. (no, unfortunately it doesn't produce pears).
When we had a pear we were told it needed a pollinator tree nearby or a branch grafted to it. We grafted Comice with Bartlett and it was wonderful. Does yours need a pollinator? Or is it just a non-fruiting variety? Beautiful photo of the vibrant leaf.
