The accolade elm is a hybrid of the species Ulmus japonica and Ulmus wilsoniana. The hybrid was introduced to take place of the American elm, whose population saw a huge decline with the introduction of Dutch elm disease.

The fruit is brown, dry and oval.
The Amur corktree is a medium sized tree 30-45’ in height. They have compound leaves with 5-11 elliptical leaflets. The upper surface of the leaf is a dark green while the lower surface is a lighter green. If crushed the leaves smell of turpentine. Cork-like bark with ridges that becomes more prominent with age. Small yellow flowers open in May and June. The fruits are clusters of pea-sized berries that mature to black in October.
The Balsam Fir has a copious amount of dark green needles which can grow up to 1 inch in length. It produces cones that are purple when young but turn brown/green and resinous as the tree matures. Moose, deer, and along with smaller woodland animals eat the buds of young cones and seeds produced by mature one. Blisters filled with oily resin can be found along its grayish trunk. It can grow anywhere from 45-70 feet in height and due to its many needles can be used in a screen or windbreak.
Black gum has ellipsoid simple leaves with a shiny luster. Fall color is full of reds and purples. Trees are male or female. The purple, paired fruits contain a large single seed.

They have alternate leaves, which are pinnately compound and 12–24 inches long. They consist of 15–23 dark green leaflets that are 2–5 inches and finely toothed. They tend to grow anywhere from 50-75 feet in heigh and produce a fleshy nut containing fruit starting from early to mid autumn. The nuts will usually not develop until the tree is 12-15 years old. It is a difficult tree to transplant from one place to another due to its long taproot.
Colorado blue spruce is a beautiful species and one of the most popular ornamental conifers in the United States. Colorado blue spruce has magnificent blue-green color with a silver shimmer.

They hang downward on the branches and are concentrated at the crown of the tree. The tallest Colorado blue spruce recorded in the United States was 100 feet tall and found in Wyoming.
Dawn Redwoods grow to be over 100 feet tall with a spread of about 25 feet at full maturity. The leaves are opposite and a fresh green color in spring in the fall the needles fade to a burnt-orange, red-brown color, older specimen form wide buttresses on the lower trunk.
