May: Flower Moon
The Full Moon of May is known as Flower Moon to signify the flowers that bloom during this month. There is a myriad of wildflowers which bloom in May in the Northern Hemisphere, where these traditional Full Moon names originated.
Lupine wildflowers start to bloom in May in North America, and may have inspired the Full Moon name Flower Moon.
This is also a Blue Moon:
A BLUE FLOWER MOON?
Traditionally, a Blue Moon was the third of four full Moons to occur within one astronomical season.
According to this definition, May’s Full Flower Moon is a Blue Moon this year! This is thanks to the timing of the March full Moon, which occurred on the same day as the Spring Equinox, and the upcoming June full Moon, which occurs just a few days prior to the Summer Solstice, making the May full Moon the third full Moon in the season of spring.
The four full Moons this spring are:
