Are red locust flowers edible and are they poisonous?
Generally speaking, red locust flowers are not edible and are toxic. Inadvertent consumption may cause physical discomfort or even poisoning. If any abnormalities occur, it is recommended to seek medical attention promptly. Detailed explanation is as follows:

Unlike commonly seen white locust flowers, red locust flowers contain certain toxins that may cause symptoms such as nausea, vomiting, and dizziness after consumption. These toxic components are harmful to the body, particularly affecting the digestive and nervous systems. Therefore, red locust flowers are usually not used as food ingredients, but rather for ornamental or industrial purposes.
There is considerable risk in mistaking red locust flowers for white locust flowers and then harvesting and consuming them. Some people may unknowingly attempt to eat them because they are unaware of the differences between the two, which could lead to poisoning. Furthermore, even small amounts of consumption might trigger allergic reactions or other adverse effects, especially in individuals with sensitive constitutions, where the consequences could be more severe.
It is important to distinguish red locust flowers from edible white locust flowers in daily life, and avoid picking or consuming unfamiliar plants randomly to ensure food safety and health.
