For the last two seasons I have picked pears from the established tree by the chicken run.  In May one of our visitors said to me “That’s not a pear tree, it’s a quince”.  I begged to differ partly because I had never seen a quince tree or its fruit and partly because I had picked, eaten, poached in wine and stored pounds of pears from the tree.  It seems that we are both correct.  On the left side of the tree hang quince fruit and on the right side hang pears.   Perhaps the pear tree was grafted onto quince stock.  Strange Fruit indeed.
