English Walnut

English walnut trees produce walnuts that have the greatest commercial value. They are large, spreading trees that grow up to 100 feet (30 meters) tall. Usually tall broad-headed trees with large leaves, gray bark, and soft wood. Most of the species are hardy, and very valuable part trees, with a massive, straight trunk, and a light and airy broad top. Though many fungi and insets prey on the walnut, none of them does very serious damage. The nuts have thin shells and taste mild and sweet. Growers typically plant English walnut trees at least 60 feet (18 meters) apart. But several varieties may be planted closer together. English walnut trees thrive in deep, well-drained, moderately moist, rich soil.
   

Hazelnut

Has a densely pyramidal form when younger, very similar to that of a littleleaf linden. It is pyramidal-oval to almost round at maturity. Considered a medium sized shade tree, the mature size is approximately 40-50 feet in height with a 20-30 foot spread.

This tree must receive supplemental watering for the first few summers. Once established it is quite drought tolerant. It is able to withstand somewhat alkaline soils but doesn’t like heavy clay soils that remain saturated.

The filbert nuts develop inside an unusual bract that is actually a modified leaf.

The attractive dark green summer foliage resembles that of a linden from a distance. The fall color is usually just a yellow-brown but a nice yellow color occurs periodically.
The tree seems to be free from insect or disease problems. Even the aphids tend to feed elsewhere. When other species such as maples and lindens display scorch symptoms, the Turkish filberts remain green and vigorous.

   

Pin Oak

Pin oaks are typically found in wet sites growing to 60' high.

They are often planted as a street tree because of their beautiful form and ability to withstand the low oxygen content of urban soils. The acorns are valuable wildlife food for wetland birds and mammals.

   

White Ash

An upland tree found in the northern hardwood forests.

Characteristics: Trees reach a height of 70-80 feet and may have a diameter of 3-7 feet.
Winged seeds are borne in clusters on the twig. These are spread by wind or water or a combination of both.

Leaves are opposite and compound with 5 to 7 leaflets which are oval and usually smooth-edged.

Smaller branches are stout, round and smooth. At the tip of the twig there are always three buds, the large, brown, pyramidal terminal and two small lateral buds. On older portions of the tree, bark is thick, dark brown, or grey and broken into flat ridges.

Because of its toughness, strength, and flexibility, the wood is used in the manufacture of athletic equipment, machinery, tools and furniture. It is a beautiful, light-colored wood with a distinctive grain.

   

Sawtooth Oak

Its dependable growth coupled with its unique form make the Sawtooth Oak a very attractive tree.

This majestic tree is perfect for lining driveways and streets, giving roads a very stately feel. They are very resistant to pollution and most diseases, which aids in its longevity.

Its glossy green leaves darken gracefully in the fall. The ends have many teeth, which give the tree the name Sawtooth.

Very popular because it is possibly the fastest growing Oak Tree. Quickly matures to a height of 60 feet.

   

Red Oak

A fast growing oak, maturing with a broad round head, leaves turning red to reddish-brown in the fall.

Will tolerate a wide range of soils mature height approximately 75-80 feet

   

White Oak

Tree develops a broad round head with spreading branches and a purple red fall color.

Leaves remain on tree in winter for landscape variety and interest. Mature height up to 100 feet. Light colored bark ands variety to the landscape.
