About

Carya cordiformis is a broad, deciduous tree that can grow to heights of 25 meters. Its large, dark green leaves, which can measure up to 30 centimeters in length, emerge from yellow winter buds and are typically composed of seven leaflets, though variations of five or nine leaflets are also observed. In spring, the tree produces yellow-green flowers, which are succeeded by nuts that are rounded or pear-shaped, measuring between 2 to 4 centimeters in length. While the nuts are edible, they possess a bitter taste.

About the genus
