Growth of cherry blossoms
The buds, basis of the cherry blossom flowers, are formed during the previous summer, and develop into flowers after going through the stages of dormancy, awakening (breaking of dormancy) and growth.
The buds enter the dormancy stage after being formed during the summer. After the awakening stage (breaking of dormancy) during the fall to winter season conditional on the degree of coldness, they start growing at the beginning of spring as the temperature increases.
