The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This full moon was known by early Native American tribes as the Flower Moon because as the season of spring progresses, the days grow longer and the weather improves, inspiring plants everywhere to “spring forth” and blossom. By May, winter’s cold grip has loosened and many plants take the opportunity to produce flowers at this time. Due to this, May’s full Moon has traditionally been known as the Flower Moon.
This moon has also been known as the Corn Planting Moon and the Milk Moon.
