Duck a l'orange and Seville Oranges
Three Christmases ago, My holiday meal was duck a l'orange. I planted the seeds from the Seville Oranges used for the recipe. They have been growing in communal pots and have postponed separating them until today. Now, I have about 30 of them--may be my New Year's Gifts for my friends. So, this Christmas more duck and another batch of seeds to plant. They grow fairly fast and seem more vigorous than Sweet Orange in my opinion. Also more cold tolerant. These are going back into a 'cold' greenhouse.
