Imperial Honeylocust (Gleditsia triacanthos 'Imperial') is a medium to large-sized tree known for its ornamental value and hardiness. It typically grows to a height of 30 to 40 feet and a spread of 35 to 50 feet at maturity. The tree has a rounded to oval crown with finely divided, bright green leaves that turn yellow in the fall, providing attractive autumn color. In the spring, it produces clusters of fragrant yellow-green flowers. Imperial Honeylocust is tolerant of a wide range of soil types and growing conditions, making it a good choice for planting in difficult sites. It is also relatively resistant to pests and diseases, including the common problem of honeylocust pod gall. Keep in mind that the growth rate and size may vary depending on the specific growing conditions and location.
