Description
Honey Locust is a medium to large deciduous tree recognized by its open, spreading crown, fine-textured compound foliage that casts light dappled shade, and often formidable branched thorns clustered on the trunk and branches (though thornless cultivars are common in landscaping). It produces fragrant greenish-yellow flowers in spring followed by long, twisted, dark brown leathery seed pods containing sweet pulp.
Habitat
Typically found in moist soils of river valleys, floodplains, and rich bottomlands, but highly adaptable to dry uplands, urban environments, and disturbed areas; requires full sun
Native Range
Native to central North America, from the Mississippi River basin west to the Great Plains, and from Ontario south to Texas; widely planted as an ornamental shade tree across North America and parts of Europe
