This Common or Persian or English Walnut is native from southeast Europe into China. It is the walnut responsible for large quantities of nuts for the market. Most are grown in the USA in California, including Zone 10 in the West, not in the East. I remember one, what we called the English Walnut, in the west suburbs of Chicago, IL that was full-grown in the backyard of a large, old house not far from where I lived. It must have been the more cold hardy variety called the Carpathian, from eastern Europe, there in Zone 5a. I've seen two trees at an old estate that is now a public park in central Chester County, PA doing well. The compound leaves of this species are 8 to 16 inches long, usually with 7 to 9 leaflets, 5 to 13 possible. The leaflets have toothless margins and are sort of rounded unlike American walnut species or hickories. The terminal leaflet is the largest. The round nuts are 1.5 to 2 inches in diameter and are surrounded by a thin, green husk. The tree tends to be rounded in habit and gets to about 70 feet high with a 3 feet diameter trunk. It is only infrequently found planted in the Midwest and Eastern US.
