American Elm - Ulmus Americana
The American Elm (Ulmus Americana) is a large, deciduous tree native to eastern North America, with a vase-shaped crown and smooth, gray bark. It has dark green leaves that turn yellow or orange in the fall. The tree produces small, winged seeds that are dispersed by the wind. It grows up to 60–80 feet tall, with a trunk diameter of up to 4 feet.
The American elm was once one of the most common trees in North America. However, it was decimated by Dutch elm disease, a fungal infection that was introduced to the United States in the early 1900s. Today, the American elm is a rare tree in many areas.
There are a number of resistant American elm cultivars that have been developed. These trees are more tolerant of Dutch elm disease, but they are still susceptible to the disease.
The American elm is a valuable shade tree. It is also a good choice for street trees and parks. The wood of the American elm is strong and durable, and it is used for a variety of purposes, including furniture, flooring, and tool handles.
The American elm is a beautiful and majestic tree. It is a reminder of a time when these trees were common in North America. With the development of resistant cultivars, the American elm may once again become a common tree in our forests and cities.
