Sophora flower, also known as acacia flower, broadly refers to the flowers and buds of leguminous plants, but generally the open flowers are called "locust flowers", also called "locust cores", and the buds are called "locust rice." It is often planted on the sides of houses and roads. It is commonly cultivated throughout China, mainly in the north, mostly on the Loess Plateau and the North China Plain. It usually blooms in April and May each year, and the flowering period is generally about 10-15 days.
