The tree produces medium to large-sized olives that are used to make green table olives. They are harvested when green, and usually pickled.
The tree is grown in Argentina, France, Israel, Italy and New Zealand.
The olives are not great for oil because they have a very low oil content. As of 2004, though, New Zealand producers are experimenting with it for oil.
Some sources say the cultivar originated in Tunisia; others say Italy.
The name “Uovo di Piccione” in Italian means “Pigeon Egg”.
