Native to Europe, but widely utilized as an ornamental garden and roadside tree, from which it easily escapes to non-cultivated areas. Now found throughout North America.


A perennial tree that can grow to nearly 100 feet in height, with extensive seedlings and root sprouts creating a problem in landscapes. Seeds form in typically pods of pea plants, and may be thrown outward as the pod opens explosively in hot weather.


Stems have short, stout spines on them as opposing pairs. Leaves are up to 8 inches long and are once or twice pinnately compound, divided into many smaller, oval leaflets. The margins of the leaflets are very slightly toothed. Flowers are in elongate clusters of small, yellowish to white pea-like flowers. The seed pod develops as a very long, twisting pod.

Characteristicts Important to Control:

Physical removal of the tree will be required, along with treatment of the stump with a registered herbicide, and follow-up treatments of new sprouts and seedlings with a systemic herbicide.
