This tree is found growing in many regions of central North America - South Dakota, New Orleans, central Texas - and towards the east, primarily in east Massachusetts.
The tree has a distinctive bark that is dark brown in color. When the tree reaches maturity, the bark becomes scaly. The trunk is short and about 3 feet in diameter. The leaves are bright green in color and are oblong in shape.
They are compound leaves that become yellow during fall. The tree grows seed pods that are about 1½ feet in size and about 2 inches wide. The seed pods contain 10-20 oval seeds that are brown in color. The fleshy part of these seed pods is sweet to taste. Hence, it is called honey locust tree. Its identification is easy because of the thorns growing on it.
It's a polygamodioecious species meaning the male and female flowers grow separately, and produce flowers on each tree. The yellow-green flowers blossom in June and bloom in 2½-inch-long clusters. The seed pods are produced when the plant reaches 10 years of age.
The second type is 'Shademaster' which is also seedless and podless. The branches of Shademaster are ascending and produce dark green leaves. The 'Majestic' is a thornless type that looks similar to your common honey locust. 'Summergold' is another variety that produces gold-green leaves during summer.
If you plan to grow this tree, you need to search for a site with well-drained soil that is moist. This tree is drought-resistant as well as flood-resistant.
The honey locust tree is grown in urban areas as it can tolerate pollution. It is also grown to control soil erosion, as a windbreaker, as well as for rehabilitation of vegetation.The wood of the tree is dense and hard. It is coarse-grained and shock-resistant. Therefore, it is used to make pallets, furniture, railroad ties, fence posts, firewood, etc.
Diseases Affecting the Tree
The most common disease that affects the tree adversely is canker. This is a fungal disease that is caused by Thyronectria austroamericana. It causes dieback of the branches, premature fall coloration, and leaf drop.
Apart from canker, this tree is also affected by root collar rot. This is a dangerous disease as it can cause the death of the tree. It causes discoloration of the bark and wood and affects the cambium of the tree. Pruning of the affected part and use of fungicides may help get rid of these fungal infections.
