If you’re looking to add a hardy, fast-growing, and often fragrant tree to your landscape, locust trees are an excellent choice. This list covers ten popular locust tree varieties for sale that suit different climates, soil types, and landscape needs. Whether you want a shade tree, a flowering specimen, or a natural fence, these locusts offer versatility and resilience for gardeners, landscapers, and tree enthusiasts.
Black Locust (Robinia pseudoacacia)
The Black Locust is native to the eastern United States and is prized for its rapid growth and durable, rot-resistant wood. It produces fragrant white flowers in late spring that attract pollinators like bees. This species tolerates poor soils and drought well, making it ideal for reclamation projects and windbreaks. However, it can be invasive in some areas due to suckering.
Honey Locust (Gleditsia triacanthos)
Honey Locust is widely planted as a shade tree because of its delicate, fern-like foliage that provides dappled shade. It grows quickly and can tolerate urban pollution, drought, and a variety of soil conditions. Many cultivars, such as ‘Sunburst’ and ‘Shademaster,’ have been developed to reduce thorns and seed pods, making them more landscape-friendly.
Prairie Locust (Robinia neomexicana)
Also known as New Mexican Locust, this smaller locust species thrives in arid and mountainous regions of the Southwest. It features showy pink to lavender flowers that bloom in late spring. Its drought tolerance and moderate size make it suitable for xeriscaping and wildlife habitat gardens.
Western Honey Locust (Gleditsia triacanthos var. inermis)
This thornless variety of the Honey Locust is especially popular in urban and suburban landscapes due to its clean appearance and minimal maintenance. It can grow up to 70 feet tall with an open canopy, providing excellent shade without overly dense foliage. Its tolerance to salt and pollution makes it a good choice for street tree planting.
Water Locust (Gleditsia aquatica)
Native to the southeastern U.S., Water Locust is adapted to wet soils and floodplains, making it ideal for planting in poorly drained or riparian areas. It has a narrower crown compared to other locusts and produces twisted seed pods. Its tolerance for wet conditions is a key reason to select this species for challenging sites.
Fragrant Black Locust (Robinia pseudoacacia ‘Frisia’)
The ‘Frisia’ cultivar of Black Locust is known for its striking golden-yellow foliage that adds color contrast in landscapes. It retains the fragrant white flowers of the species and the same fast growth habit. This variety is popular for ornamental use in parks and large gardens due to its unique leaf color.
Texas Honey Locust (Gleditsia × texana)
A natural hybrid between Honey Locust and Texas native species, Texas Honey Locust exhibits exceptional drought tolerance and adaptability to alkaline soils. It has a broad, spreading canopy and typically fewer thorns than wild types. This hybrid is valued in southern U.S. landscapes for shade and erosion control.
Bristly Locust (Robinia hispida)
Bristly Locust is a shrub-like species native to the southeastern U.S., recognized for its attractive pink to purple pea-like flowers. It grows up to 15 feet tall and is often used in native plant gardens or as a natural hedge. Its tolerance to poor soils and ability to fix nitrogen improve soil quality where planted.
Yellow Locust (Robinia pseudoacacia ‘Bessoniana’)
This Black Locust cultivar is distinguished by its bright yellow flowers, which bloom profusely in late spring. It shares the species’ fast growth and hardiness but offers a unique floral display for ornamental planting. It performs well in USDA zones 4 through 8 and tolerates urban conditions.
Prairie Acacia (Robinia neomexicana ‘Prairie Rose’)
A selected form of Prairie Locust, ‘Prairie Rose’ is noted for its vibrant rosy-pink flowers and compact growth habit. It is well-suited for dry, rocky soils and attracts pollinators such as bees and butterflies. This variety is excellent for xeriscapes and naturalized areas in the southwestern U.S.
How to Choose
When selecting a locust tree, consider your local climate and soil conditions first. Black Locusts thrive in a variety of soils but can spread aggressively, so they’re best where naturalization is desired. Honey Locusts and their cultivars are more urban-friendly with thornless varieties and manageable seed pods. If you have wet or poorly drained soil, Water Locust is a better fit. For ornamental value, cultivars like ‘Frisia’ or ‘Bessoniana’ add color interest. Also, think about mature size and maintenance needs: some locusts grow tall and wide, while others remain shrub-like. Finally, check for local regulations as certain locusts are invasive or restricted in parts of the U.S.
Frequently Asked Questions
Are locust trees invasive? Black Locust can be invasive in some regions because it spreads by root suckers and seeds, outcompeting native plants. Honey Locust is generally less invasive but seed pods can be messy. Always check local guidelines before planting.
Do locust trees attract pollinators? Yes, locust species like Black and Prairie Locust produce fragrant flowers favored by bees, butterflies, and other pollinators, making them beneficial for local ecosystems.
How fast do locust trees grow? Most locust trees are fast growers, often adding 2 to 3 feet per year under good conditions. Black Locust is among the fastest, reaching maturity in 10 to 15 years.
Are locust trees good for shade? Honey Locusts are excellent shade trees due to their open, airy canopy that allows filtered light. Black Locusts also provide shade but tend to have denser foliage.
What soil conditions do locust trees prefer? Locusts are adaptable but generally prefer well-drained soils. Water Locust can tolerate wetter soils, while Prairie Locust thrives in dry, rocky areas.
Do locust trees require much maintenance? They are relatively low maintenance but Black Locust may need control due to suckering. Honey Locust cultivars require less pruning and produce fewer seed pods, reducing cleanup.
Final Thoughts
Locust trees are a versatile group offering options for shade, ornamental beauty, and ecological benefits. From the hardy and fragrant Black Locust to the urban-tolerant Honey Locust cultivars, there is a locust tree suited to nearly every landscape and climate.
