This tree is native to Europe and Asia, with a form similar to another common tree used in the urban setting, the Little Leaf Linden.   The shape is oval to broadly pyramidal.  Mature height is 40 to 50 feet, depending on exposure and resources.  The bark is grayish and corky, becoming flaky with age.  This usually exposes nicely contrasting orange or brown inner bark.

This tree deals well with Boulder, Colorado’s Hardiness Zone 4, drastic temperature extremes and strong snow storms, the Chicago area Hardiness Zone is Zone 5. Turkish Filbert is an increasing component of the Boulder parkway tree planting list.  Once established, it is quite drought and alkaline soil tolerant.  It usually remains green and vigorous under such conditions while other much more common species such as Maples and Lindens are more likely to display leaf scorch symptoms.

Turkish Filbert seems to largely remain free from insect or disease problems, although occasionally Japanese beetles will take some bites if near adjacent infested species such as Lindens and Crabapples.

Finally, this tree produces a small edible nut inside two spiky husked sepals.  Usually squirrels and wildlife harvest all in late September.

So if you’re tired of the same old repeatedly planted mosaic of Linden, Maple, Honey Locust etc., Turkish Filbert is a choice addition for increased diversity.
