Description
Gleditsia triacanthos is a deciduous tree reaching 20-25 m (66-82 ft) in height, occasionally up to 30 m (98 ft), with a trunk diameter up to 1 m (3.3 ft). The crown is broad and irregular, with pinnate or bipinnate compound leaves 15-25 cm (6-10 in) long, depending on sunlight exposure and tree age. The foliage turns bright yellow in autumn. The bark is gray-brown and becomes deeply fissured with age. One of its most distinctive features is the presence of large, branched thorns, sometimes over 20 cm (8 in) long, that emerge from the trunk and branches. The tree produces fragrant greenish-yellow flowers in late spring, followed by long, twisted brown seed pods 20-40 cm (8-16 in) in length containing sweet, edible pulp.
Native to central and eastern North America, from southeastern South Dakota and Pennsylvania south to Texas and northern Florida, Gleditsia triacanthos naturally inhabits floodplains, riverbanks, and open woodlands on well-drained alluvial soils. It is highly adaptable to a wide range of environmental conditions, including drought, poor soils, and urban settings, which has contributed to its widespread cultivation and naturalization outside its native range.
