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.
