Botanical description:

Honeylocust is a native, deciduous tree. Mature heights usually range from 49 to 98 feet (15-30 m), with a maximum height of 140 feet (43 m). In natural stands, honeylocust averages 70 to 80 feet (21-24 m) in height. Honeylocust is armed with heavy branched thorns on the lower branches and trunk. The crown is plumelike and open. The bole is usually short and often divided near the ground. The bark of mature trunks is usually 0.25 to 0.75 inches (0.6-3.5 cm) thick with narrow ridges divided by fissures. The bark peels in strips. The thick, fibrous roots are deep and wide-spreading. The tree is sturdy and windfirm. The fruit is a legume 8 to 16 inches (15-40 cm) long and 1 to 1.4 inches (2.5-3.5 cm) wide.
Honeylocust is usually described as rapid-growing. The average longevity for honeylocust is 125 years.
Unlike most leguminous species, honeylocust does not form Rhizobium nodules on its roots and does not fix nitrogen.

Seasonal development:

Honeylocust begins to flower when its leaves are nearly full-grown, from around May 10 in the southern parts of its range to around June 25 in the northern parts of its range. The legumes ripen from September to October, usually falling after ripening but sometimes remaining on the tree through February.
