Whether you’re seeking an attractive addition to your garden or looking to utilize the benefits of their wood, locust trees offer a compelling choice.
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 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.
The honey locust tree, also known as Gleditsia triacanthos, is native to North America. It can be found in various regions across the continent, including the eastern United States and parts of Canada.
One of the notable benefits of the honey locust tree is its ability to provide shade. Its large, spreading canopy offers relief from the sun during hot summer months. This makes it popular for landscaping in parks, residential areas, and other outdoor spaces.
In addition to its shade-providing qualities, the honey locust tree also offers other benefits. Its wood is highly durable and resistant to decay, making it valuable for construction. The tree’s thorns, although they can be sharp and intimidating, serve as a defense mechanism against grazing animals, protecting the tree from harm.
Interestingly, the honey locust tree has an important ecological role as well. Its flowers attract bees, which in turn helps with pollination. The tree’s pods, which contain seeds, are also a food source for various wildlife, including birds and small mammals.

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.
Can I plant a locust tree near my house?
You can plant a locust tree near your house if you choose an appropriate location. Remember that some species of locust trees have aggressive root systems that may cause damage to foundations or underground utilities over time. You should consult a professional arborist or landscaper who can assess your situation and recommend suitable tree species for planting near structures.
How fast do locust trees grow?
Locust trees are known for their rapid growth rate. They can grow between 2-3 feet per year under ideal conditions. However, growth rates may vary depending on soil quality, sunlight exposure, and water availability.
Do all locust trees have thorns?
No, not all varieties of locust trees have thorns. While some species, like the black locust (Robinia pseudoacacia), have sharp thorns, others, such as the honey locust (Gleditsia triacanthos), are thornless. When selecting a locust tree for your landscape, you can choose a thornless variety if you prefer to avoid dealing with thorns.
How do I care for a locust tree?
Locust trees generally require minimal care once established. Provide them with regular watering during dry spells and ensure they receive adequate sunlight. Pruning should be done in late winter or early spring to remove dead or damaged branches and maintain an open canopy structure. It’s recommended to consult with an arborist for specific care instructions based on the type of locust tree you have.
Are locust trees good for attracting wildlife?
Yes, locust trees can attract various types of wildlife. The flowers of certain species, like the black locust, are known to attract bees and butterflies due to their nectar production. The seeds and pods produced by some locust trees serve as a food source for birds and small mammals. Planting a locust tree in your yard can help create a habitat that supports local wildlife populations.
Can I use wood from a locust tree for construction projects?
Yes, locust wood is highly durable and resistant to rotting and decay. It is often used in outdoor construction projects such as fencing, decking, or furniture making. Locally sourced locust wood is preferred due to its sustainability and reduced environmental impact compared to imported alternatives.
Do all varieties of locust trees produce flowers?
No, not all varieties of locust trees produce flowers. While some species, like the black locust, are well-known for their fragrant white flowers that bloom in springtime, others may not flower at all or produce inconspicuous blooms that go unnoticed.
