I have a few hundred Hardy Orange (Poncirus trifoliata) thanks to a previous owner who did not keep them bush-hogged out of a cattle pasture.  I have eliminated about half of them so far.
Per some discussions on this site a couple years ago, I harvested ripe fruit in September from many of the trees, looking for ones with fewer seeds and less bitter pulp.  There was very little difference between all the fruit I tested.  It is intensely flavored, but makes good lemonade (1 tbsp juice to a cup of sugar and a cup of water).  I made some good marmalade from the peel and juice, but I have not bothered to repeat it.
The peel contains a sticky white sap until the fruit is dead ripe.
Cut branches and trunks, after drying for a week, are so high in oil content, they burn as if they had been soaked in gasoline!
