In autumn, 3-4-year-old stone flowers open yellow, white, red, pink, purple and other flowers from the top and middle gap of opposite leaves. One plant usually only opens one flower (less 2-3 flowers), mostly in the afternoon, close in the evening, and open again in the afternoon the next day. A single flower can open for 7-10 days. The flower diameter is 3-5cm. When flowering, the flower covers almost the whole plant, which is very delicate. After the flower withers, it bears fruit and can harvest very small seeds.
The body of raw stone flower contains a lot of water. Under the strong light, it looks crystal clear and beautiful.
