The flowering period of roses is from May to September every year. In some warm places, roses can bloom in April. From the beginning of spring, roses can continue to bloom for about half a year. Rose flowers like a well-lit, warm and humid environment. Rose flowers grow vigorously in spring and bloom brilliantly in summer.

Rose flowers are usually clustered in clusters of 6 to 7, and panicle-shaped umbels grow on the tops of branches. They are most commonly red or pink. Most of the rose flowers are vine-climbing florets. The diameter of the flowers is about 3 cm, blooms once a year. After blooming, the leaves fall off, and the leaves are alternate and have serrated edges.
