Springtime was a season that took place on some planets, for example, Lothal, and was one of four.
Traditionally, the coming of springtime on Lothal was announced by the arrival of warmer temperatures and the smells of things like jogan flowers carried by the wind. But, because the Galactic Empire was mining and poisoning the atmosphere, there were awful dust storms and colder temperatures during the time of year when springtime should have been at its peak. An old poet named Holshef remembered when you could recognize the beginning of springtime by the green color of the grasslands and the aroma of arrack vine and jogan on the wind coming from the west.
