Key Differences
Honey locust (Gleditsia triacanthos) trees feature a lighter, more open canopy compared to the dense, leafy coverage of black locust (Robinia pseudoacacia) trees. This difference in foliage affects the amount of shade each tree provides, with honey locust offering dappled sunlight and black locust creating more substantial shade.
The thorns of these species are notable distinctions. Honey locusts can have large, branched thorns on their trunk and branches, making them somewhat intimidating, though thornless varieties are commonly planted in urban areas. Black locust trees have smaller, simpler thorns that are nonetheless sharp, primarily found on the younger trees or new growth.
In terms of flowering, black locust trees are admired for their attractive, fragrant white flower clusters that bloom in late spring. Honey locust trees, however, have less conspicuous flowers, which are followed by the distinctive flat, twisted seed pods that can litter the ground in autumn.
The wood of black locust is highly valued for its durability and resistance to rot, making it a popular choice for furniture, fencing, and small watercraft. Honey locust wood, while also durable, is not as commonly used for these purposes due to its less consistent density and hardness.
Environmental adaptability shows another contrast; honey locust trees are extremely tolerant of urban pollution, poor soils, and drought conditions, making them favorites for city landscaping. Black locust, while also resilient, is considered invasive in some regions due to its aggressive root system and rapid growth, which can outcompete native vegetation.
