Let’s take a look at some of the Locust Tree Types:
Different Types of Locust Trees
List of Locust tree types discussed in this post:
- Black Locust.
- Honey Locust.
- Purple Robe Locust.
- Golden Locust.
- Thornless Honey Locust.
- Bristly Locust.
- Sunburst Locust.
- Shademaster Locust.
Black Locust

Black locust trees, scientifically known as Robinia pseudoacacacia, are native to the southeastern United States. Despite their name, black locust trees are not locusts but belong to the pea family. These trees are known for their striking appearance, with a tall and upright growth habit, reaching heights of up to 80 feet.
One of the significant benefits of black locust trees is their ability to fix nitrogen in the soil. They have specialized bacteria in their root nodules, which can convert atmospheric nitrogen into a form other plants can use. This makes black locust trees excellent for improving soil fertility and promoting healthy plant growth in their vicinity.
In addition to their nitrogen-fixing capabilities, black locust trees offer a range of other benefits. They have dense and durable wood, making them highly valued for construction and woodworking. The wood is resistant to rot and decay, making it ideal for outdoor applications such as fence posts, decking, and furniture.
Interestingly, black locust trees have a long history of use in traditional medicine. Various parts of the tree, including the bark, leaves, and flowers, have been used in herbal remedies for treating ailments such as respiratory issues, digestive disorders, and skin conditions. However, these remedies should be used under the guidance of a qualified healthcare professional.
Another fascinating aspect of black locust trees is their ability to spread rapidly. They have an extensive root system that allows them to colonize disturbed areas and outcompete other plant species. This can be both beneficial and problematic, depending on the context. While their ability to quickly establish themselves can help prevent soil erosion, they can also be invasive in specific ecosystems.
Compared to black locusts, cedar trees, known for their natural resistance to decay and insect infestation, may not be as durable and require more maintenance over time. Black locust is often considered stronger and more durable than cedar.

Appreciating the Beauty of Locust Trees, But Beware of the Risks
Now that we’ve explored different types of locust trees, it’s clear that these trees possess a unique beauty that can enhance any landscape. Their vibrant flowers and lush foliage make them popular for homeowners and garden enthusiasts. However, knowing the potential risks associated with locust trees is essential.
Locust trees, with their vibrant flowers and lush foliage, are undoubtedly a beautiful addition to any landscape. However, it’s important to note that they can also be high-maintenance. These trees require regular pruning to maintain their shape and prevent overgrowth. Additionally, some species of locust trees are susceptible to certain diseases and pests, such as locust borers or cankers. It’s crucial to stay vigilant and monitor the health of your locust tree to address any issues promptly. Regular inspections and proper care can help ensure the longevity and beauty of these trees in your yard.
Another factor to consider when planting a locust tree is its potential impact on nearby structures. Locust trees have a strong, durable wood that makes them highly resistant to decay and rot. While this is desirable for the tree, it can pose a risk to buildings, fences, or other nearby structures. The root systems of locust trees are also known to be aggressive, potentially causing damage to underground pipes or foundations. Before planting a locust tree, it’s essential to consider the distance from structures and plan accordingly to minimize potential risks.
In conclusion, while locust trees offer aesthetic appeal and are attractive to any landscape, weighing their potential risks is essential. Before choosing to plant one, consider your local environment and ensure you can manage its growth and maintenance effectively.
