Description
The honeylocust is a medium to large deciduous tree known for its dappled shade, open canopy, and famously formidable branched thorns on the trunk of wild types (though thornless cultivars are common in landscaping). It produces fragrant greenish-yellow flowers, followed by large, twisted, flat leathery brown pods containing sweet pulp.
Habitat
Found naturally in moist bottomland soils along streams, but highly adaptable to urban environments, poor soils, drought, and varying pH levels
Native Range
Native to central North America, ranging from the Ohio and Mississippi river valleys west to the Great Plains, and widely planted as an urban shade tree across North America and parts of Europe
