Slightly bitter and slightly sweet, walnuts lend their distinct flavor to muffins, breads, salads, mezze and other dishes. Walnut trees grow throughout much of the United States and vary widely in their annual growth rate.

Black Walnut

The black walnut tree (Juglans nigra) has a mature height of 50 to 75 feet and can grow in hardiness zones 4 to 9. As a medium grower, this type of walnut averages 12 to 24 inches of new growth per year.

Carpathian English Walnut

The Carpathian English walnut (Juglans regia 'Carpathian') grows in hardiness zones 5 to 9. It has a faster annual growth rate of 25 inches per year, but only reaches 40 to 60 feet in height.

White Walnut

The white walnut (Juglans cinerea) also reaches a maximum height of 40 to 60 feet, but has a slower growth rate of 12 inches per year. This tree grows in hardiness zones 3 to 7.
