Honey locust trees are a popular choice for landscapes due to their delicate foliage, adaptability, and unique seed pods. This list covers the most common and distinctive honey locust tree types, perfect for gardeners, landscapers, and tree enthusiasts looking to add texture and shade to their outdoor spaces. Each variety offers different traits, from thornless forms to varied growth habits, helping you find the ideal match for your environment.
1. Gleditsia triacanthos (Common Honey Locust)
The species Gleditsia triacanthos is the wild form native to central North America. It is characterized by its large, spreading canopy, bipinnate leaves, and formidable thorns on the trunk and branches, which can grow up to several inches long. This tree produces long, twisted seed pods that are a food source for wildlife but can be a nuisance in lawns. It is valued for its toughness and rapid growth in a variety of soil conditions but less commonly planted in urban settings due to its thorns.
2. Gleditsia triacanthos var. inermis (Thornless Honey Locust)
This thornless variety is the most popular cultivated form, prized for its lack of the large spines that characterize the species. It has a graceful, open canopy with fine-textured, fern-like leaves that provide dappled shade, making it ideal for parks and large yards. The ‘inermis’ variety produces fewer seed pods, which reduces litter, and is highly tolerant of urban pollution, drought, and poor soils. Cultivars like ‘Skyline’ and ‘Shademaster’ fall under this category and are widely used in street and commercial plantings.
3. Gleditsia triacanthos ‘Skyline’
‘Skyline’ is a thornless cultivar known for its upright, columnar form, reaching heights of 40 to 70 feet with a narrower spread than the species. Its dense, feathery foliage turns a bright yellow in fall, offering striking seasonal color. This cultivar is favored in urban landscapes where space is limited but shade is desired. It also shows strong resistance to pests and diseases common to honey locusts.
4. Gleditsia triacanthos ‘Shademaster’
‘Shademaster’ is another thornless cultivar, distinguished by its broad, rounded crown that can spread wider than ‘Skyline.’ It typically grows 30 to 50 feet tall and is known for its vigorous growth and drought tolerance. This variety is often chosen for large residential yards or parks needing a substantial shade tree with minimal maintenance. It produces abundant, finely divided leaves that create a soft, filtered light effect.
5. Gleditsia triacanthos ‘Imperial’
The ‘Imperial’ cultivar is a thornless honey locust that grows with a more upright and symmetrical habit than the species. It reaches heights of 35 to 50 feet and features bright green foliage that turns golden yellow in autumn. ‘Imperial’ is appreciated for its clean appearance, reduced seed pod production, and adaptability to urban soils. Its moderate size and neat form make it a versatile choice for street tree planting.
6. Gleditsia triacanthos ‘Moraine’
‘Moraine’ is a thornless cultivar noted for its dense, upright branching and bright green leaves. It tends to grow slightly faster than some other cultivars and can reach 40 to 50 feet tall. This variety has excellent tolerance to drought, heat, and salt, making it suitable for challenging urban or roadside environments. Its fall color is a striking yellow, adding seasonal interest to landscapes.
7. Gleditsia triacanthos ‘Sunburst’
‘Sunburst’ is a thornless variety prized for its vibrant yellow-green new foliage that emerges in spring before maturing to a darker green. It grows quickly to about 30 to 40 feet tall with a broad, spreading canopy. This cultivar is especially valued for ornamental use in parks and large gardens due to its colorful foliage and tolerance of a wide range of soil types. It also produces fewer seed pods than the species.
8. Gleditsia triacanthos ‘Ruby Lace’
‘Ruby Lace’ is a distinctive cultivar selected for its burgundy to deep red foliage that holds color through the growing season. It typically grows 25 to 35 feet tall with a rounded crown and fine-textured leaves. This variety adds a striking visual contrast in mixed landscapes and is often used as an accent tree. It requires full sun and well-drained soil to maintain its vivid leaf color.
9. Gleditsia triacanthos ‘Skycole’
‘Skycole’ is a thornless cultivar similar to ‘Skyline’ but with a more compact, oval shape. It grows 30 to 50 feet tall and is known for its dark green foliage and strong branching structure. This variety is popular for urban settings where a smaller footprint is required but shade and ornamental value remain priorities. It is also resistant to common honey locust pests and diseases.
10. Gleditsia triacanthos ‘Shademaster’ (Drought Tolerant Clone)
A specific clone of ‘Shademaster’ has been selected for enhanced drought tolerance, making it especially valuable in regions with dry summers or water restrictions. This cultivar maintains its lush foliage and vibrant fall color even under limited irrigation. It combines the broad canopy and rapid growth of ‘Shademaster’ with improved resilience, ideal for sustainable urban landscapes.
How to Choose
When selecting a honey locust tree type, consider the presence or absence of thorns, which significantly affects maintenance and safety. Thornless cultivars like ‘Skyline’ or ‘Shademaster’ are preferable for residential and urban areas. Evaluate the tree’s mature size and shape to ensure compatibility with your space—upright forms suit narrow lots, while broader canopies provide more shade. Also, consider seed pod production; many cultivars have reduced pods to minimize litter. Climate tolerance, soil adaptability, and pest resistance are vital for long-term success, especially in urban or drought-prone environments. Finally, think about ornamental traits such as fall color or unique foliage, which can enhance landscape aesthetics.
