Robinia hispida is a salt-and-alkali-resistant woody flowering plant.

Robinia hispida, also known as Jiangnan locust, is a deciduous shrub in the genus Robinia of the Fabaceae family. Its stems, branchlets, pedicels and petioles all bear red bristly hairs, hence the name Robinia hispida. Its leaves resemble those of black locust (Robinia pseudoacacia), with alternate odd-pinnate compound leaves and broadly elliptical leaflets. The papilionaceous corolla is pink or purplish red. The flowering period is in May, and the pods mostly do not develop. For propagation of Robinia hispida, black locust is commonly used as rootstock for "cleft grafting". Generally, high-branch grafting is chosen. After surviving, it grows very quickly, and the crown spreads outward in an umbrella shape, bearing flowers all over the tree in the second year, which is very beautiful. Artificially, Robinia hispida can be made to bloom twice a year by cutting off all the shoot tips of the branches in early to mid-June after the first flowering in spring, prompting it to send out new branches, whereupon flower buds appear in large numbers in early July for a second flowering.

Robinia hispida is a tree species for courtyard greening and beautification. Its flowers are large and beautiful, it has strong cold and drought tolerance, strong adaptability to soil, grows and takes shape quickly, tolerates pruning well, has strong sprouting ability, and has strong resistance to smoke, dust and toxic gases such as hydrogen fluoride and ozone. Notably, its rootstock is black locust, so it possesses some of the excellent characteristics of black locust and has a very strong salt-and-alkali resistance. According to measurements, it still grows well in soil with a salt content of 7‰-9‰, making it a good tree species for landscaping in saline-alkali areas.
