Note to self: Do not plant Trifoliate orange where it would require pruning! Wearing gloves and a heavy jacket were not much protection from these thorns!
It tends to grow into a large and tangled mess. Fragrant, typical citrus blooms in the Spring are followed by golf ball size, sour and seedy, oranges. You can use them in drinks or some other recipe where you need a sour citrus. When the fruits fall to the ground the seed germinate easily so I collect them and either throw them in the garbage or you can let them dry to use for decoration.
