Attributes:
The Thornless Honeylocust is a widely planted landscape tree. Its tolerance to the stresses of urban conditions partially accounts for its popularity, especially its ability to withstand drought and to grow under a wide range of soil conditions. It is also said to be one of the most salt-tolerant trees, standing up well even along Chicago's freeways. Another feature is its remarkable growth rate. Newly planted trees can be expected to add 2 feet or more per season for at least the first 10 years. Finally, the open crown of the Honeylocust allows enough light to filter through to favor the growth of grass beneath its branches.
