How many sepals are there in sunflower?
It can vary
The main idea is that there is no set number of sepals in a sunflower. Imagine that would be like asking how many seeds are produced from a sunflower. Keep in mind that you must consider all the various heads on a given flower (the flower in this sense being the entire plant). That number of sepals in a sunflower can vary. Needless to say, you must then consider the size of the head (s). It is essential to understand that the size of the head will have an important effect on the number of stamens.
