This issue involves the growth habits and biological characteristics of sunflowers. Firstly, we need to be clear: the name of a sunflower does imply a special relationship between it and the sun, which is "born in the morning sun.". But this does not mean that the sunflower flowers will follow the sun from east to west every day
In fact, the flower disc of sunflowers does exhibit a tendency towards the sun during its early growth. This is because in the morning, the sunflower's disk will face east, and as the sun moves, it will gradually turn, making the disk face the sun. However, this rotation is not continuous. Once the flower disc of a sunflower matures and begins to seed, it stops its heliotropic rotation and is fixed in one direction
So, although the name and growth habits of sunflowers give people the impression of being born in the morning, in reality, they do not strictly follow the sun's movement from east to west every day. Its heliotropism is mainly manifested in the early stage of growth, and at the mature stage, the flower disc will be fixed in one direction
In summary, sunflowers do exhibit a certain degree of heliotropism in the early stages of growth, but they do not grow strictly at sunrise every day
