What is a black locust tree?
Black locust (Robinia pseudoacacia) is an invasive species in California . This tree grows up to 100 feet tall and produces leaf stems with seven to 19 oval-shaped leaflets. At the base of each leaf grows a spine or pair of spines. Black locust has been used in some states to control erosion because of its rapid growth. It prefers well-drained soils and full sun. In addition to its invasive status in California, this tree may also be considered a nuisance by property owners because of its rather large seed pods -- up to 4 inches long -- and thorns.

What is the most difficult invasive tree to eradicate?
Black locust (Robinia pseudoacacia), also called false acacia or yellow locust, is one of the most difficult invasive trees to eradicate.

Planted outside of its native range for hardwood lumber and fence posts, erosion control, reclaiming of mine soil, and as nectar for honeybees, it was noted in Michigan’s jack pine barrens by 1888, and in Washtenaw County by 1862. Because black locust fixes nitrogen in the soil and spreads clonally by suckers, it can form dense colonies that overshade and outcompete native species.
How does removal of sprouts help clones grow?

Black Locust Tree Facts
Growth Rate – Black Locust Trees can grow up to 4′ per year when young. Typically 2′ per year once several years old.

How to identify Black Locust Trees
Mature Black Locust Trees will grow on average 50′-80′ tall (15m-24m) and have an irregular crown shape. The branching on a Black Locust tree is typically upwards.
Thorns
Thorns occur along the smaller branches and twigs which are about 1/2″ long, and occur in pairs. These thorns are quite sharp, and can cause minor injury if you grab a branch or sapling.
Leaves
Black Locust Tree leaves are compound alternate leaves in an overall arrangement that is approximately 6-18″ long by ~4″ wide. The individual leaflets are about 1-2″ long by roughly half as wide, with a rounded shape. Leaves will have a light green color early, changing to blueish-green color when mature.
Flowers
In late Spring on Black Locust Trees, groups of white flowers will form and hang down from the branches in beautiful arrangements. The overall cluster will be 4-7″ long, and look like dangling cluster of pea-like flowers that are very fragrant. An individual flower is approximately 1″ long with 5 petals that are white in color.
Seed Production
The flowers will give way to seedpods that are approximately 2-4″ long by 1/2″ wide and hang down much like the preceding flowers. Each pod will contain roughly 2-12 seeds that are hard, 1/4″ diameter, and have a rounded shape but very flat.
