Hi,
I don't know if you are looking for a specific type of sour orange, but I have a small Seville orange that has a few fruit starting to color up (first from this tree) and I don't have plans for all of them. There are just few, but if you could use some please let me know. (I am assuming that they will be seedy--never have seen a fresh one.)
Also, I have a couple of Chinotto oranges that will have fruit, but I suspect they won't be ready for a while--about olive-sized now. If you'd like some of those in a few months, you are also welcome.
BTW this is a great forum.
