The bark is deeply furrowed and is brown and gray. Due to orangey-red colors in the deep grooves, the bark may have an overall reddish appearance.

The black locust tree bark is not sharp and thorny like the honey locust tree. The honey locust tree is a hardy, fast-growing tree, similar to the black locust tree. Just like the black locust, the species of honey locust grows in many different environments and thrives in full sun. Similar to the black locust tree, this genus is native to states such as Pennsylvania, Iowa, Texas, and Georgia.

Honey locust trees grow to between 66 and ft. Unlike the black locust, the honey locust tree trunk has thorny branches growing around it. In a garden landscape, honey locust trees are grown as specimen trees for their ornamental beauty. Bright green foliage turns a beautiful yellow color in the fall. Seed pods, or legumes, mature in early fall. These are sweet-tasting peas that animals enjoy eating. The honey locust has clusters of small, creamy-green flowers that bloom in late spring and early summer.

However, both the Robinia and Gleditsia species of locust trees have strongly scented blossoms. The leaves on honey locust trees appear slightly earlier than on black locust trees.

One way to tell honey locusts apart from black locust trees is that the leaves have no leaflet at the tip. The imperial honey locust tree is a thornless species of deciduous tree that grows up to 40 ft. The fact that this locust tree has no thorns and a wide-spreading canopy means it is a great shade tree for your garden. Similar to other types of locust trees, the imperial honey locust has beautiful fern-like foliage that turns to sunny yellow in the fall.

The trees are also resistant to saline conditions, lack of water, and high winds. The flowers are small clusters of greenish-white florets that bloom in late spring and early summer. The feather-like leaves are pinnately compound that are bright green throughout spring and summer before turning to golden yellow in the fall. The tree grows to 45 ft. The fern-like leaves and widely spaced branches give enough shade without completely blocking out sunlight.

One of the reasons this locust tree variety is popular is that it grows in several unfavorable conditions. It can withstand high heat, full sun, acidic or alkaline soil, and urban pollution.

Greenish-white, inconspicuous flowers appear in May and June and turn into long twisted seedpods that are a purple color. These pods contain a sweet, honey-like substance as with all honey locust trees. Leaves on the skyline honey locust tree are pinnate or bipinnate containing pairs of small, ovate leaflets. Dark green leaves in the summer turn in to attractive yellow foliage in fall. If you want a thornless variety of skyline locust tree, look for the Gleditsia triacanthos f.

The New Mexico locust tree is also called the southwestern locust or hojalito. The New Mexico locust tree grows to between 16 and 32 ft. Late spring and early summer bring out the beautiful fragrant purple-pink clusters of flowers on this locust tree. These attractive blooms attract honey bees who are looking for nectar. These showy flowers grow on reddish-purple branches that have spikes at their base.

The sweet-smelling, fragrant flowers are light purple and shades of pink. This flower color is unusual for trees in the genus Robinia as the flowers are commonly white. Facebook Twitter LinkedIn Email.

Kyle Felling was born in the rugged northwest Missouri hamlet of St. Joseph where the Pony Express began and Jesse James ended. Inspired from a young age by the spirit of the early settlers who used St.

Joseph as an embarkation point in their journey westward, Kyle developed the heart of an explorer and yearned to leave for adventures of his own. Perhaps as a result of attending John Glenn elementary school, young Kyle dreamed of becoming an astronaut, but was disheartened when someone told him that astronauts had to be good at math.

He also considered being a tow truck driver, and like the heroes of his favorite childhood television shows The A-Team and The Incredible Hulk he saw himself traveling the country, helping people in trouble and getting into wacky adventures.

Most fruit tend to ripen in late October and can last on the branches until early spring. There is an average of 25, seeds per pound. Research Natural range of distribution: Habitat: Black locusts are native to the United States but the extent of its original range is not completely known. It is however, though to be originally found in two regions-- the eastern and western region. The eastern region centered in the Appalachian Mountains and this range spanned from central Pennsylvania, southern Ohio to northwestern South Carolina and northern Georgia.

The western region centered around the Ozark Plateau in southern Missouri and ranged towards the the Ouachita Mountains of central Arkansas and southeastern Oklahoma. Black locusts have been heavily distributed across North America since their origin because they have been widely planted and is able to avoid cultivation. They are native to a broad range of forest types and conditions, however, they thrive within the cove or mixed-mesophytic forests of the central and southern Appalachian region.

They are well adapted to many soils but cannot survive on permanently wet; they most prefer moist, loamy soils of limestone origin. They were able to exist in all states within the native range with the exceptions of Illinois, Pennsylvania, South Carolina, and Georgia.

Origin, history, and uses: The wood of the black locust has been used by humans throughout history and typically was used for mine props, railroad ties and fence posts. Native Americans used the locust for their bows and other tools. It was favored heavily in colonial times and is considered one of the strongest North American timbers, helping to build Jamestown and ships during the War of Because they are transplanted easily, they also serves a large role in preventing soil erosion as well as for ornamental purposes street-trees.
